[PATCH 2/3] AM_PROG_CC_C_O: don't rely on AC_PROG_CC_C_O, re-implement similar logic

** Theoretical problems of AC_PROG_CC_C_O: Both cc and $CC are checked to see if they support the '-c' and '-o' options together. This behaviour is highly inconsistent with that of the other macros related to C compiler checks -- which test only $CC. It can also cause unwarranted uses of

[PATCH 1/3] compile: rewrite AC_PROG_CC with AM_PROG_CC_C_O contents

This is a much simpler rewrite than the one we attempted in the past, and that was later removed by commit 'v1.13.1d-137-g32eb770' of 2013-05-11 (compile: avoid AC_PROG_CC messy rewrite). Not only this change simplifies the code a little, but has the welcome collateral effect of making automatic d

[PATCH 3/3] tests: some tests make no sense if "$CC -c -o" doesn't work

So just skip them, to avoid spurious failures when running "make check-no-cc-c-o". * t/ax/am-test-lib.sh (require_tool): New requirement '-c-o'. * t/subobj10.sh ($required): Add it. * gen-testsuite-part (%depmodes): Adjust so that tests that use 'makedepend' will be skipped if the compiler is bein

[PATCH 0/3] Last work on AM_PROG_CC_C_O, AC_PROG_CC, "$CC -c -o"

I will push these three patches to maint (so that they'll end up in Automake 1.14) in one or two days. A review would be welcome. Regards, Stefano -*-*-*- Stefano Lattarini (3): compile: rewrite AC_PROG_CC with AM_PROG_CC_C_O contents AM_PROG_CC_C_O: don't rely on AC_PROG_CC_C_O, re-imple

And do so in a safer way, with a runtime check rather than a brittle static maintainer check. * t/ax/test-init.sh: Set the 'required' variable to readonly. * syntax-checks.mk (sc_tests_required_after_defs): Remove. (syntax_check_rules): No longer list it. Signed-off-by: Stefano Lattarini --- sy

[FYI] {micro} tests: use append mode to capture parallel make output

This will allow us to run the Automake testsuite forcing all the make invocations in the test cases to run in parallel mode [1], but without hitting the spurious failure reported in automake bug#11413. See also: The make invocatio
