__sparcv9 is defined only for 64-bit builds, it is not defined for 32-bit
builds.
#ifdef guarding on __sparcv9 only will result on (APR_IS_BIGENDIAN == 0) for
32-bit sparcv8 builds.
the correct #ifdef guard should be:
#if defined(__sparc) || defined(__sparcv9)
/* ... */
#endif
/* testsparcdefines.c */
#include <stdio.h>
static char* endian = "LITTLE ENDIAN";
int
main(int argc, char* argv[])
{
#if defined(__sparcv9)
endian = "BIG ENDIAN";
#endif
(void) fprintf(stderr, "endian is %s.\n", endian);
return 0;
}
