Bug in Hooks patch

[Steven Edwards]

Hello,
I am trying to build quake 2 on Mingw using a dsw2mak converter and 
Brain Hooks patch. I didnt know where to report bugs.

qcommon/common.c:941: conflicting types for `SZ_Write'
qcommon/qcommon.h:88: previous declaration of `SZ_Write'
make: *** [qcommon/common.o] Error 1

Seem that

common.c has
void SZ_Write (sizebuf_t *buf, void *data, int length)

and qcommon.h has
void SZ_Write (sizebuf_t *buf, const void *data, int length);

I would like to get quake2 to build under Mingw as I want to test on 
ReactOS and try to build as a winelib applications
Thanks
Steven
