[Bug 54858] ld duplicate

--- Comment #1 from Eric Bolinger <bo...@pobox.com> ---
FYI, I fixed this problem locally by modifying the ap_config.h include file. 
The source contains some comments about NeXT gcc missing the inline and
__attribute__ feature.  Because of the NeXT/Apple entanglements, I guessed at
adding "defined(DARWIN)" as a condition for declaring ap_inline:




#if !defined(__GNUC__) || __GNUC__ < 2 || \
    (__GNUC__ == 2 && __GNUC_MINOR__ < 7) ||\
    defined(NEXT) || defined(DARWIN)
#define ap_inline
#define __attribute__(__x)
#define ENUM_BITFIELD(e,n,w)  signed int n : w
#else
#define ap_inline __inline__
#define USE_GNU_INLINE
#define ENUM_BITFIELD(e,n,w)  e n : w
#endif


I did not add this condition to other declarations, so YMMV.

This worked for Apache HTTPD version 1.3.42 built on Mac OS X 10.9.2,
mavericks.
