|

* Test release 2.10.1.
|
||||
|
||||
* acspecific.m4 (AC_PROG_CC_WORKS, AC_PROG_CXX_WORKS): New macros
|
||||
adapted from Jim Meyering and automake.
|
||||
(AC_PROG_CC, AC_PROG_CXX): Use them.
|
||||
* acgeneral.m4 (AC_TRY_RUN_NATIVE): Split out of AC_TRY_RUN.
|
||||
(AC_TRY_LINK): Check that the executable exists after linking.
|
||||
(AC_EGREP_CPP): Disable m4 quote chars around egrep, so [] in regexps
|
||||
isn't eaten.
|
||||
|
||||
* autoheader.sh: Add multiple-inclusion protection for config.h.
|
||||
|
||||
* acgeneral.m4 (AC_PREFIX_PROGRAM): Pretty up the output.
|
||||
(AC_CHECK_LIB): Include the function being tested in the message.
|
||||
(AC_CHECK_PROG, AC_PATH_PROG): Add a dummy variable to force word
|
||||
splitting on the path.
|
||||
|
||||
* acspecific.m4 (AC_FUNC_MMAP): Remove check and uses of valloc.
|
||||
It turns out it's a separate issue, for GNU grep.
|
||||
Replace the test program with a new version from Mike Haertel.
|
||||
|
||||
* acgeneral.m4 (AC_CACHE_SAVE): Accept the HP-UX sh 'set' output
|
||||
format. From Marcus Daniels <marcus@sysc.pdx.edu>.
|
||||
|
||||
* acgeneral.m4 (AC_MSG_CHECKING, AC_CHECKING): Write a message to
|
||||
config.log also. From "T.E.Dickey" <dickey@clark.net>.
|
||||
(AC_CHECK_LIB, AC_CHECK_HEADER, AC_CHECK_HEADERS): Replace use of
|
||||
tr with sed, to avoid a bug in the AIX 4.1.3.0 tr reported by
|
||||
Alain KNAFF <Alain.Knaff@imag.fr>. He says that version of
|
||||
tr interprets \055 magically like an unquoted -.
|
||||
* acspecific.m4 (AC_PROG_MAKE_SET, AC_CHECK_HEADER_DIRENT,
|
||||
AC_CHECK_HEADERS_DIRENT): Ditto.
|
||||
|
||||
* acspecific.m4 (AC_FUNC_SETPGRP): New macro.
|
||||
* acconfig.h (SETPGRP_VOID): New entry.
|
||||
From "T.E.Dickey" <dickey@clark.net>.
|
||||
|
||||
* acspecific.m4 (AC_PATH_X_DIRECT): Try /lib/usr/lib/X11 for A/UX.
|
||||
From Guillermo Gomez <gomez@mi.uni-erlangen.de>.
|
||||
(AC_PATH_XTRA): Replace -R with LD_RUN_PATH in the
|
||||
Solaris kludge. From Paul Eggert <eggert@twinsun.com>.
|
||||
|
||||
(AC_PATH_XTRA): Replace -R with adding LD_RUN_PATH to CC in the
|
||||
Solaris kludge. Suggested by Paul Eggert <eggert@twinsun.com>.
|
||||
Define X_DISPLAY_MISSING with AC_DEFINE, and
|
||||
if not using X, clear out the X variables.
|
||||
Check system-dependent libs before system-independent ones.
|
||||
Check for more system-dependent libs.
|
||||
From Karl Berry.
|
||||
Use AC_CHECK_FUNC in the system-dependent libs tests.
|
||||
From Larry Schwimmer <rosebud@cyclone.stanford.edu>.
|
||||
Wart removal: Don't require AC_ISC_POSIX.
|
||||
(AC_ISC_POSIX): Don't blather about being called before AC_TRY_LINK,
|
||||
which is now called in AC_PROG_CC. Don't encourage using this macro.
|
||||
* acconfig.h (X_DISPLAY_MISSING): Add entry.

Here is a matrix of mmap possibilities:
|
||||
mmap private not fixed
|
||||
mmap private fixed at somewhere currently unmapped
|
||||
mmap private fixed at somewhere already mapped
|
||||
mmap shared not fixed
|
||||
mmap shared fixed at somewhere currently unmapped
|
||||
mmap shared fixed at somewhere already mapped
|
||||
For private mappings, we should verify that changes cannot be read()
|
||||
back from the file, nor mmap's back from the file at a different
|
||||
address. (There have been systems where private was not correctly
|
||||
implemented like the infamous i386 svr4.0, and systems where the
|
||||
VM page cache was not coherent with the filesystem buffer cache
|
||||
like early versions of FreeBSD and possibly contemporary NetBSD.)
|
||||
For shared mappings, we should conversely verify that changes get
|
||||
propogated back to all the places they're supposed to be.
|
||||
|
||||
Grep wants private fixed already mapped.
|
||||
The main things grep needs to know about mmap are:
|
||||
* does it exist and is it safe to write into the mmap'd area
|
||||
* how to use it (BSD variants) */

Here is a matrix of mmap possibilities:
|
||||
mmap private not fixed
|
||||
mmap private fixed at somewhere currently unmapped
|
||||
mmap private fixed at somewhere already mapped
|
||||
mmap shared not fixed
|
||||
mmap shared fixed at somewhere currently unmapped
|
||||
mmap shared fixed at somewhere already mapped
|
||||
For private mappings, we should verify that changes cannot be read()
|
||||
back from the file, nor mmap's back from the file at a different
|
||||
address. (There have been systems where private was not correctly
|
||||
implemented like the infamous i386 svr4.0, and systems where the
|
||||
VM page cache was not coherent with the filesystem buffer cache
|
||||
like early versions of FreeBSD and possibly contemporary NetBSD.)
|
||||
For shared mappings, we should conversely verify that changes get
|
||||
propogated back to all the places they're supposed to be.
|
||||
|
||||
Grep wants private fixed already mapped.
|
||||
The main things grep needs to know about mmap are:
|
||||
* does it exist and is it safe to write into the mmap'd area
|
||||
* how to use it (BSD variants) */
