  Ok, I set the INCLUDES in src/Makefile to add d:/mingw/include and
d:/mingw/include/sys (which I didn't think would be necessary since
cygwin usually selects the correct header set based on -mno-cygwin) and
 then put all files back to original.

  The gcc -E output shows:
int __attribute__((__cdecl__)) mkdir (const char*); (looks like mingw
io.h)
and calls like:
status = mkdir (file_name, mode ^ invert_permissions);

  I changed the #define for system.h to be:
#define mkdir(file, mode) (mkdir(file))

and the module compiles:
$cd src;gcc -mno-cygwin -DHAVE_CONFIG_H -I. -I. -I.. -
I../lib -I../lib -Id:/mingw/include -Id:/mingw/include/sys
-I/usr/include -I/us
r/include/sys    -g -O2 -MT extract.o -MD -MP -MF ".deps/extract.Tpo"
-c -o ext
ract.o `test -f 'extract.c' || echo './'`extract.c; cd ..
extract.c: In function `extract_archive':
extract.c:722: warning: assignment makes pointer from integer without a
cast

  As far as pwd.h and grp.h, mingw (windows native) doesn't have the
same notion of user password and group password in the /etc/passwd
sense so maybe this should somehow not be required for mingw.

thx,
