thanks for the answers. gcc fortran compilers support -o -c, however without the AM_PROG_F*_C_O the .o files are produced in the build directory and not in the subdirectory. AC_PROG_F*_C_O is not enough to guarantee this. I am using libtool 1.5.8 on Darwin 8.2.0 powerpc. Best regards

speaking about this, are there Fortran or F77 compilers which are not
able to interpret -c -o? msg00210.html has a really old example. I'd expect other really old compilers to also
have this limitation, but could not name one which is in common use.

OK, so it seems that the macros

 -- Macro: AC_PROG_F77_C_O
 -- Macro: AC_PROG_FC_C_O

should stay in Autoconf, but the doc might say that these days it is safe
to suppose that -c -o just works.

And there is no need why Automake could think about the issue.
There is no need for any AM_* counterpart for these macros.

Thanks for your information,
