Bugzilla Bug 67016

I don't have the 'zlib' useflag set, and every 'emerge gnome' (or 'emerge
vino') gave the following final output:

gcc -DHAVE_CONFIG_H -I. -I. -I../.. -Wall -Wmissing-prototypes -O2 -c zrle.c

Clearing use and cflags doesn't solve the problem, however, 'USE="zlib" emerge
vino' does.

It seams that in ./server/libvncserver/zrle.c, the zrleData member of the
rfbClientPtr struct and the two functions ('rfbSendRectEncodingZRLE' and
'FreeZrleData') are only avalible if HAVE_LIBZ is defined in
./server/libvncserver/rfb/rfb.h, which requires zlib to be included.

Reproducible: Always
Steps to Reproduce:
1.ACCEPT_KEYWORDS=~x86 emerge gnome (or)
2.ACCEPT_KEYWORDS=~x86 emerge
3.

Actual Results:

worked for the 2.7 series im pretty sure. Ok, for now we just disabled the zlib
flag.

Thanks for the report.
