`AC_PREREQ'. * tests/tools.m4: Globally, don't use `../' to invoke the tested tools, since the PATH is properly set, and in most cases it obfuscates the test code. (autoupdating AC_PREREQ): New tests.

# The test `syntax.m4' tries to run all the macros of Autoconf to check
|
|
# for syntax problems, etc. Not all the macros can be run without argument,
|
|
# and some are already tested elsewhere. EGREP_EXCLUDE must filter out
|
|
# the macros we don't want to test in syntax.m4.
|
|
#
|

# - AC_CANONICALIZE, AC_PREFIX_PROGRAM, AC_PREREQ
|
|
# Need an argument.
|
|
# - AC_CHECK decl, file, func, header, lib, member, prog, sizeof, type
|
|
# Performed in the semantics tests.
|
|
# - AC_CONFIG
|
|
# They fail when the source does not exist.
|
|
# - AC_INIT
|
|
# AC_INIT includes all the AC_INIT macros. Note that there is an
|
|
# infinite m4 recursion if AC_INIT it used twice.
|
|
# - AC_LANG*
|
|
# Heavily used by other macros.
|
|
# - AC_PATH_PROGS?, AC_F77_FUNC
|
|
# They produce `= val' because $1, the variable used to store the result,
|
|
# is empty.
|
|
# - AC_TRY, AC_.*_IFELSE
|
|
# Used in many places.
|
|
# - _AC_
|
|
# Internal macros are used elsewhere.
|
|
# - AC_OUTPUT
|
|
# Already tested by `AT_CHECK_MACRO'.
|
|
# - AC_FD_CC
|
|
# Is a number.
|
|
# - AC_PROG_CC, AC_C_(CONST|INLINE|VOLATILE)
|
|
# Checked in semantics.
|
|
# - AC_CYGWIN, AC_CYGWIN32, AC_EMXOS2, AC_MING32, AC_EXEEXT, AC_OBJEXT
