# NOTE: with gcc-3.4.0, linux-libc-headers-2.6.5.1 on 
#       biarch x86_64-pc-linux-gnu the build barfed out with
#       errors in lib/regex.c due to conflicting types for
#       malloc. removed definitions of malloc/realloc and
#       made it so stlib.h always gets read.
#
#     : same results with linux-libc-headers-2.6.6.0 with
#       gcc-3.4.1-20040620 on x86_64-pc-linux-gnu
#
# TODO: check if other architecturess are affected, and for what
#       glibc/gcc/m4 versions.
#
#     : same issue w powerpc...
#
#       Get a better fix for this....
