  To: gcc-bugs

with the gcc-4.5-20100325 (and predecessors) I am facing this kind of
builderrors when cross-building:
...

# If this is the top-level multilib, build all the other
# multilibs.
# Recursively invoke make in the GCC directory to build any
# startfiles (for now).  We must do this just once, passing
# it all the GCC_EXTRA_PARTS as simultaneous goal targets,
# so that rules which cannot execute simultaneously are properly
# serialized.  We indirect through T_TARGET in case any multilib
# directories contain an equals sign, to prevent make from
# interpreting any of the goals as variable assignments.
# We must use cd && make rather than make -C, or else the stage
# number will be embedded in debug information.

../../gcc-4.5-20100325/gcc/system.h:199:22: fatal error: strings.h: No such
file or directory


This error originates from this call to gcc carrying build-host include search
directories in its search path.

This shows in this case, because the build-host has both "strings.h" and
"string.h" while the target only has "string.h" and because the bogus include
search path causes compilation to pull-in a build-host's config.h (from
libcpp).
