Description:
------------
bz2 extension header causes php_bz2_filter_factory symbol to be a common symbol, rather then extern variable, due to lacking 'extern' modifier. When compiling on Mac OS X, which uses -fno-common by default, this causes build failure. The header should define it just as extern, since the symbol is properly declared in bz2_filter.c.

Fix:
