Hello,
xlf has two pecularities, I found out about the hard way, which might break
_AC_PROG_FC_V_OUTPUT:
1. The list of flags is not only comma-separated but also enclosed in
parentheses. This is fine as long as the last argument is of no import to the
linker, but in case it is and is picked up by _AC_PROG_FC_V_OUTPUT, all kinds of
"funny" errors result.
2. The -ipa step adds a -link option which must not be used from the front-ends
and is mistaken for a request to link libink.a.
I've attached a patch to fix these issues in the version I found in the
repository at git://git.sv.gnu.org/autoconf today.
Greetings, Thomas
