Dear Fortran maintainers, dear autoconf gurus, The attached patch replaces the deprecated AC_TRY_{COMPILE,LINK,RUN} macros in libgfortran configury with their AC_*_IFELSE equivalents. Now (4.7 just branched) seems a good time, and I think I didn't screw it too much because the regenerated configure file only has whitespace changes. Still, I'd like to have the opinion of a build maintainer or autoconf guru.
Bootstrapped and regtested on x86_64-darwin. OK to commit to trunk?
