[cups-devel] cups #defines __attribute__ to be empty

OpenJDK builds use the __attribute__ keyword to indicate symbols are
exported
However cups/versioning.h #defines this to be empty unless the compiler
is GNU C.
See the last few lines here :
https://github.com/apple/cups/blob/master/cups/versioning.h
So in our code when we include cups/cups.h cups we lose the value of
__attribute__
and you only find out at runtime when these symbols are loaded via JNI and
we get a linkage error.
Why is CUPS doing this ?
And more importantly can it be fixed ?
