autoconf/tests/Makefile.am
Akim Demaille 7435a2e96c Simplify the interface: users shouldn't need to explicitly check
for special environments.

* acspecific.m4 (AC_EXEEXT, AC_OBJEXT): AU defined to
nothing.  Replace them by...
(_AC_EXEEXT, _AC_OBJEXT): this.
* aclang.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_F77): Call them.
(AC_PROG_CC_G, AC_PROG_CXX_G, AC_PROG_F77_G): Rename as...
(_AC_PROG_CC_G, _AC_PROG_CXX_G, _AC_PROG_F77_G): this.
Adjust dependencies.
* tests/Makefile.am (FILTER_MACROS): Adjust.
* doc/autoconf.texi (Compilers and Preprocessors): New section,
move the documentation of AC_PROG_CC, AC_PROG_CC_C_O,
AC_PROG_CC_STDC, AC_PROG_CPP, AC_PROG_CXX, AC_PROG_CXXCPP,
AC_PROG_F77, AC_PROG_F77_C_O, AC_PROG_GCC_TRADITIONAL here.
Factor the comment documentation of AC_PROG_CC, AC_PROG_CXX,
AC_PROG_F77.

# FILTER_MACROS
# -------------
# 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
# Needs 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?
# 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_TEST_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
# AU defined to nothing.
#
# Multiple `-e' to egrep are not portable, so join all the patterns together.
# We use the fact that automake will replace all the `\\\n' with ` '.
