Bugzilla Bug 9446

zsnes-1.36 will not build on my 1.4_rc1 machine (though it builds on another
one
of my 1.4_rc1 machines).  One machine is a Pentium3, the other is an Athlon-XP,
other than that they have the same CFLAGS (not that the zsnes build pays
attention to your CFLAGS).  The Pentium3 build works, Athlon-XP breaks.  Mayhap
a gcc bug?  I dunno.  gcc output follows. 

gcc -pipe -I. -Wall -D__LINUX__ -I/usr/X11R6/include -I/usr/include/SDL
-D_REENTRANT -D__OPENGL__ -Os -ffast-math -fomit-frame-pointer
-fschedule-insns2
-s -march=pentiumpro -o zip/zzip.o -c zip/zzip.c

can you try a:
   cd /usr
   find . -name unzip.h

and tell me if it finds unzip.h anywhere?

Nope, not found.  Nor does updatedb && locate unzip.h

Okay, I figured out how to fix this, but I don't know how or why my fix works.
On a whim, I deleted every instance of the word ZEXPORT from src/zip/unzip.[ch],
and now it compiles and runs fine.  gcc bug?  configure bug?  I don't know
enough C to be able to tell you.

*** Bug 10119 has been marked as a duplicate of this bug. ***

try deleting these 2 files and emerging zsnes again 
/usr/X11R6/include/{zconf.h,zlib.h} 

That fixes it.

fix is in cvs, enjoy
