well, glew will "define" every possible extension (e.g.
"GL_APPLE_texture_range" will be defined), since this is a preprocessor
thing and would just be an annoyance for a runtime checker.
the clause
<snip>
#ifdef GL_APPLE_texture_range
#endif
</snip>
has to be replaced by
<snap>
if (GLEW_APPLE_texture_range){
}
</snap>
if this is what you meant by having "to clean up some code based on
platform assumptions in order to make it work", then i'd answer "YES".
btw, welcome to the joys of compiling things on platforms where the
headers do not exactly match the installed libraries....
