FWIW, this is how current CVS (during the last few weeks) plus Paul's pending gnulib additions fares on these systems: (sorted by OS then CPU; no comment means no failures; using the native compiler if present, GCC on the w32-based ones; GNU m4 everywhere, but otherwise native tools; no special CFLAGS etc.) powerpc-ibm-aix4.3.3.0 powerpc-ibm-aix5.1.0.0 powerpc-ibm-aix5.2.0.0 powerpc-ibm-aix5.3.0.0 i686-pc-cygwin OK with a (completely) binmounted cygwin. With text mode mounts I got several failures. Somebody should test this, maybe it was just my cygwin setup being broken. How could one change this quickly without a full reinstall and regedit? powerpc-apple-darwin8.2.0 i386-unknown-freebsd5.4 hppa2.0-hp-hpux10.20 hppa2.0w-hp-hpux11.00 hppa2.0w-hp-hpux11.11 hppa2.0w-hp-hpux11.23 ia64-hp-hpux11.23 mips-sgi-irix6.5 i686-pc-linux-gnu OK for several different distributions hppa2.0-unknown-linux-gnu x86_64-unknown-linux-gnu OK with GCC, Portland (5.2, 6.0, 6.1), Intel 9.0. x86_64-unknown-linux-gnu with Pathscale compiler has two failures: 110: GNU Fortran 77 111: GNU Fortran because the compiler tricks configure into thinking it's the GNU compiler, but actually has a different flag for free-form. Probably safest to fix the test rather than the macro? i686-pc-mingw32 i386-unknown-openbsd3.8 alphaev5-dec-osf4.0d alphaev67-dec-osf5.1 sparc-sun-solaris2.6 sparc-sun-solaris2.7 sparc-sun-solaris2.8 sparc-sun-solaris2.9 sparc-sun-solaris2.10 It also passes maintainer-check and distcheck on i686-pc-linux-gnu.
