Hi folks,

Trying to compile Wireshark (SVN) on my Solaris 9 system is giving me this error:
gcc -DHAVE_CONFIG_H -I. -I. -I. -I/usr/local/include -I/usr/local/include -Werror "-D_U_=__attribute__((unused))" -g -O2 -Wall -W -Wdeclaration-after-statement -Wendif-labels -Wpointer-arith -Wbad-function-cast -Wcast-qual -Wwrite-strings -Wstrict-prototypes -Wmissing-declarations -Wcast-align -I/usr/local/include/glib-1.2 -I/usr/local/lib/glib/include -I/usr/local/include -I/usr/local/include -MT libwiretap_la-file_access.lo -MD -MP -MF .deps/libwiretap_la-file_access.Tpo -c file_access.c  -fPIC -DPIC -o libwiretap_la-file_access.o
file_access.c: In function `wtap_dump_file_write':
file_access.c:952: warning: passing arg 2 of `gzwrite' discards qualifiers from pointer target type
Which doesn't make sense to me because (from the pre-processed but 
not-yet-compiled file):
extern int gzwrite (gzFile file, const voidp buf, unsigned len);

size_t wtap_dump_file_write(wtap_dumper *wdh, const void *buf, unsigned bufsize)

 if(wdh->compressed) {
  return gzwrite(wdh->fh, buf, bufsize);
What am I missing here?
