[Xcb] How supported is Windows/MinGW?

[David Gerard]

I'm trying to build xcb on MinGW. (A quixotic project to build libX11
and thence Wine. It's my holidays, it relaxes me.) See
http://wiki.winehq.org/WineOnWindows#head-5c33720da11a0bf4bf1d942e4b5864b9ce0cc7eb

I understand MinGW is a supported platform. At least ./configure gives
that impression. But I can't get it to compile. I tried using
pthreads.h from Pthreads Win32, and the make bombs out with:

make  all-am
make[1]: Entering directory `/home/fun/libpthread-stubs-0.1'
if /bin/sh ./libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I.
-I. -I.     -g -O2 -MT stubs.lo -MD -MP -MF ".deps/stubs.Tpo" -c -o
stubs.lo stubs.c; \
then mv -f ".deps/stubs.Tpo" ".deps/stubs.Plo"; else rm -f
".deps/stubs.Tpo"; exit 1; fi
mkdir .libs
 gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -MT stubs.lo -MD -MP -MF

Please submit a full bug report,
with preprocessed source if appropriate.

make: *** [all] Error 2

What intuitively obvious thing have I missed?
