Somehow, this necessary patch was only applied to the 3.2 and 3.3 release branches. The RTEMS community has skipped the 3.4 branch so never noticed it missing there. Anyway, it never got on the head.
http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/config/rs6000/sysv4.h?rev=1.113.4.1&content-type=text/x-cvsweb-markup We didn't notice it until we were paying attention to RTEMS build failures. The toolset will build without this but isn't functional. Is this OK to merge? -- Summary: RTEMS CPP specs not merged from 3.2/3.2 branches Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: joel at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org,ralf dot corsepius at rtems dot org GCC target triplet: powerpc-rtems http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19548
