There's a typo in CFLAGS.
At this point in the configure script, CC may be one of user-provided
$CC, $F77, $FC, $GCJ,
$ac_ext will be adjusted to the current language, as will $ac_compile,
so I don't think this makes too much sense.
I think you wanted $LTCC $LTCFLAGS instead.
(Or $ac_compile in conjunction with $lt_simple_compile_test_code? But
then, the cache variable should be tagged.)
Surely you get away with this because, after the C case is tested,
AC_CACHE_VAL causes the test not to be executed again. So you may
simply m4_if([$1], [], [
AC_CACHE_VAL(...)])
to make clear that it is your intent to only run in the C case, and just
remove that code from the other tags. Do you agree?
I'm happy to leave it as is, simply changing to LTCC and LTCFLAGS in all
cases. If the var happens to become unset somewhere then the test will run
again. I'll put it on my "fixme sometime" list though.
Applied the following to fix the typo.
