Hello Ralf, I'll address PR 492 in its thread, lest the mixup of threads and topics be un-disentangle-able. ;-)

Well the Automake test suite does not test that Automake's handling of source files named *.S actually works as expected. So far it only tested *.s. This is a bug from the perspective that the testsuite should be as comprehensible as possible, ideally covering each code path. So I created asm2.test, which is very similar to asm.test, but deals with *.S instead of *.s, and adjusted the details. The new test exposes the issue that, if you AC_SUBST the variables CCAS and CCASCOMPILE, then you get a cryptic warning: > > > > > /opt/gnu/share/automake-1.9c/am/depend2.am: am__fastdepCCAS does not > > > > > appear in AM_CONDITIONAL > > - above warning is suboptimal because there is too little help > > (the other warnings you posted had help, but were only present > > in the test case). So the change to automake.in fixes the warning to (hopefully) be more informative. > > Further note a small buglet in m4/as.m4: > > - without no-dependencies, we should not compute depmode. > Could you elaborate what this issue is you are trying to fix? > I must be missing something. Certainly. This issue only showed up for me during testing of the patch. If the Automake option no-dependencies was used, the the dependency style should not be computed. Here's a proto testsuite addition to expose this (note the `exit 1' before you copy and paste this in your running shell) that exposes the bug: cat >configure.ac <<\EOF AC_INIT([asm-nodep], 1, [devnull]) AM_INIT_AUTOMAKE([foreign no-dependencies]) AC_CONFIG_FILES([Makefile]) AM_PROG_AS AC_OUTPUT EOF cat >Makefile.am <<\EOF bin_PROGRAMS = foo foo_SOURCES = foo.S EOF : >foo.S aclocal automake -a autoconf ./configure | tee stdout grep 'dependency style' stdout && exit 1 : Cheers, Ralf
