48656aea07 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Set FPATH too. 
Problem reported by Fred Kreek in
<http://lists.gnu.org/archive/html/bug-autoconf/2007-06/msg00009.html>.
* doc/autoconf.texi (Special Shell Variables): Warn about FPATH.
(Macro Names, Defining Directories): Don't mention PATH as a name
for a fully qualified file name, as this usage violates the GNU
coding standards and we shouldn't recommend it.

* lib/autotest/general.m4 (AT_INIT): Don't set PATH to the empty
string and then assume shell builtins like "test" will work.

12bfe452a5 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp

the parens work with Emacs.

cadaf30a72 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look 
for a.* when searching for executables, as this prevents users
from having files like a.c.  Problem reported by Ralf Wildenhues in:

c470a65ca3 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris

4ccb447218 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF, 
AC_CHECK_TYPE, AC_CHECK_TYPES.
* doc/autoconf.texi (Generic types): C types must be type-names
(the C terminology), not type-ids (the C++ term).  C++ types
must not be anonymous.
* lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
for C++; this drops support for anonymous struct and union types,
which were problematic anyway.
* tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
for C++.

d09b879309 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK): Fix AC_CONFIG_LINKS 
to prefer a link source from the build tree, if it exists.

fb82e1a122 * doc/autoconf.texi (Generic Types): Document the restrictions 
on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
(Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
with objects too.  Document the restrictions on its use.
Document the restrictions on AC_CHECK_ALIGNOF's type argument.
* lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
works but the latter doesn't, then it's a valid type.
This lets people use function types and so forth.
For C++ there doesn't seem to be a simple solution, so leave it alone.
(AC_CHECK_SIZEOF): Allow argument to be a variable.
(AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
AC_CHECK_TYPE; that wasn't documented or necessary.
