I tried to build the lto branch as of 20090709 on IRIX 6.5 with GCC 3.4.5 as
bootstrap compiler. The build fails like this:
% gcc -c -g -fkeep-inline-functions -DIN_GCC -W -Wall -Wwrite-strings
-Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute
-Wold-style-definition -fno-common -DHAVE_CONFIG_H -I. -I.

While the native IRIX 6.5 stdint.h could be used with -std=c99 (or gnu99), this
will fail completely on platforms that lack stdint.h completely. Using a
sufficiently new gcc as bootstrap compiler that provides stdint.h itself would
be a workaround, but gcc is supposed to be buildable with any C90 compiler.
