[MPlayer-cygwin] MinGW compile-problem in vd_lcl.c, missing definition of 'Z_NO/BEST_COMPRESSION'

[Stefan Gürtler]

Hi
Lately I am unable to compile mplayer under MinGW, no matter how many
options I disable. Both mplayer-1.0pre3 and latest source from cvs.
Both give me an error (see first paragraph blow ) due to missing definitions
for `Z_NO_COMPRESSION' and `Z_BEST_COMPRESSION' in the file vd_lcl.c. (see
second  paragraph blow)
I have browsed the includes of vd_lcl.c and found all include-files on my
system expect of zlib.h.
HAVE_ZLIB is undefind in config.h.
There is another "reference" to 'Z_NO_COMPRESSION' in vo_png.c, but there it
is not defined, but used.(see third paragraph)
Where is the definition of 'Z_NO_COMPRESSION' and `Z_BEST_COMPRESSION' on
your systems? Is it in zlib.h, and who do I get it?

Some information on MinGW:
I am using a fresh installation of MSys 1.09 and MinGW 3.1.0-1. I tryed the
included gcc version 3.2.3 (mingw special 20030504-1) and the update gcc
version 3.3.1 (mingw special 20030804). Only the directx7-header were added
to mingw includes.
Tests were done on a PIII with Win98 and on a P4 with WinXP.

Yours Stefan
