Not directed at you in particular, and I understand that.

See patches 1-4. These are the missing syscalls.
According to what orc was saying, patch 1 was what he needed for Xorg.
Gregor also said he could use it.

orc would know better than I, but it *seemed* that he was saying that

See patches 5-10 (except the finite() patch)
I figured that any *isoc99* or __*_internal aliases were for ABI only and
left them as orc had it.
Everything in src/locale/ I assumed (!) was not ISO C99, and did them "in
