cygwin build problem: sys/bitypes.h: No such file or directory

[Brian Dessent]

I'm running into the following trying to build current texinfo CVS HEAD
on Cygwin:

if gcc -DHAVE_CONFIG_H -I. -I. -I../..  -I../../intl   -g -O2 -MT
error.o -MD -MP -MF ".deps/error.Tpo" -c -o error.o error.c; \
        then mv -f ".deps/error.Tpo" ".deps/error.Po"; else rm -f
".deps/error.Tpo"; exit 1; fi
In file included from /usr/include/cygwin/types.h:21,
                 from /usr/include/sys/types.h:373,
                 from /usr/include/stdio.h:46,
                 from error.c:28:
./stdint.h:79:26: sys/bitypes.h: No such file or directory
make[3]: *** [error.o] Error 1
make[3]: Leaving directory `/usr/src/texinfo/gnulib/lib'

I'm at a loss as to what this means, maybe a problem with the gnulib
stdint module?  The above is the result of:

cvs -d :pserver:address@hidden:/sources/texinfo co texinfo \
  && cd texinfo \
  && ./autogen.sh \
  && ./configure -C --enable-maintainer-mode \
  && make

The full configure/build log is at
<http://dessent.net/tmp/texinfo_build.log> if it helps.  The line:

checking absolute name of <stdint.h>... ///usr/include/stdint.h

...did catch my eye as being possibly an issue, but I'm not sure if
that's relevant.
