When compiling libssp, ssp.c, function __guard_setup:
O_RDONLY is undeclared (ssp.c:93:34),
ssize_t is an unknown type name (ssp.c:96:7), and
size_t is an unknown type name (ssp.c:113:25).

A bootstrap C compiler is generated properly when passing --without-headers.
I can provide more details and command output. Recently I was able to
get 6.3.0 as close to working with Newlib 2.5 as I can tell, so this
is not extremely urgent. Unfortunately I may have other questions
about earlier GCC versions.
Any suggestions related to generating cross toolchains, specifically
generating a toolchain close to the one found at
https://developer.arm.com/open-source/gnu-toolchain/gnu-rm, would be
extremely helpful. Any help provided will be used to better support
for generating toolchains with the crossdev project.
I am very confused and what I want to do seems to be poorly documented.
Thanks in advance,
