Description Kai Sterker 2010-01-05 10:04:05 UTC 
Build of SDL 1.3 rev 5441 broken on OSX 10.4.11. I get

libtool: compile:  gcc -g -O2 -I./include -maltivec -DTARGET_API_MAC_CARBON -DTARGET_API_MAC_OSX -fvisibility=hidden -I/usr/X11R6/include -D_THREAD_SAFE -falign-loops=16 -force_cpusubtype_ALL -fpascal-strings -MMD -MT build/SDL_cpuinfo.lo -c src/cpuinfo/SDL_cpuinfo.c  -fno-common -DPIC -o build/.libs/SDL_cpuinfo.o
src/cpuinfo/SDL_cpuinfo.c: In function 'SDL_GetCPUCount':
src/cpuinfo/SDL_cpuinfo.c:313: error: '_SC_NPROCESSORS_ONLN' undeclared (first use in this function)
src/cpuinfo/SDL_cpuinfo.c:313: error: (Each undeclared identifier is reported only once
src/cpuinfo/SDL_cpuinfo.c:313: error: for each function it appears in.)
make: *** [build/SDL_cpuinfo.lo] Error 1

Unlike 'man 3 sysconf' suggests, there is no such definition in unistd.h. Haven't digged much, but Google seems to confirm that.

I guess configure.in needs a special check for this case, so that HAVE_SYSCONF will not be set when it shouldn't be. (manually changing include/SDL_config.h accordingly got me over this issue)

This is fixed in revision 5443, thanks!
