More specifically I created a makefile that included the /sys and /bsd
include files in the posix library. The berkely libsocket library I am
using is a highly modified version of the originaI with much better
socket support. I also did some rather ugly commenting in and around the
win32 sections which I will clean up later and perhaps add a UEFI define
of some sort :) There were some ssize_t and int issues as well. I will
try to configure cygwin and see what I get.

I had not, but I tried it now and I still get the same errors. My cflags
for building the library are: C_FLAGS = /D __STDC__ /D
"BUILDING_LIBCURL" $(C_FLAGS)
Perhaps there is something else I am missing, I will check to see what
other static options I can set.

have a sneaky suspicion the indenting is going to look weird. If so,
apologies in advance!
