Background: I tripped over a grub bug in Fedora Core 3 on x86_64 (actually, probably any arch with NX support). It was suggested that I fetch and build the rawhide version of grub to see if the problem has been fixed. See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=147392 It turns out that the latest version of the grub SRPM will not build on FC3. This seems very unfortunate. I would consider it a bug. Is this known? Intended? A good thing? Details: I fetched http://download.fedora.redhat.com/pub/fedora/linux/core/development/SRPMS/grub-0.95-12.src.rpm Trying to build it on FC3 x86_64 + updates failed with errors: checking for C compiler default output file name... configure: error: C compiler cannot create executables Reading config.log, I see instead a couple of compiler errors. Both suggest that a different version of gcc was expected: configure:2396: gcc -V </dev/null >&5 gcc: `-V' option must have argument configure:2425: gcc -m32 -Os -g -fno-strict-aliasing -Wall -Wno-pointer-sign -Werror -Wno-shadow -static conftest.c >&5 cc1: error: unrecognized command line option "-Wno-pointer-sign" I got the same errors in FC3 i386 + updates.
