Re: Compile problem under Linux Fedora 5

Hmm, I have a sneaky suspicion that they finally made JB_SP a private
definition in new version of glibc (2.4). It's still defined =20
internally in
sysdeps/i386/jmpbuf-offsets.h

Simple fix is to add this missing macro in md.h in the LINUX section:

#elif defined(__i386__)
#define MD_STACK_GROWS_DOWN

#if defined(__GLIBC__) && __GLIBC__ >=3D 2
#ifndef JB_SP
/* =46rom sysdeps/i386/jmpbuf-offsets.h in glibc 2.4 */
#define JB_SP 4
#endif
#define MD_GET_SP(_t) (_t)->context[0].__jmpbuf[JB_SP]
#else

Please give it a try.  If it works, we'll add this to the next ST =20
release.
Thanks!
