Ahh, didn't realize that WORDS_BIGENDIAN was being generated by
autoconf. The offending code would appear to be in the LAM source
acconfig.h, it looks like some confusion over #if's and #ifdef's, and an
incorrect workaround.
<SNIP acconfig.h>
/*
* Grumble. AC_C_BIGENDIAN #defines WORDS_BIGENDIAN to 1 if we're on
* a big endian machine. But it leaves it undefined if we're on a
* little endian machine (same for HAVE_YIELD). This causes "gcc
* -Wundef" to complain when we use "#if WORDS_BIGENDIAN". So #define
* it here to be 0 if it isn't already defined.
*/
#ifndef WORDS_BIGENDIAN
#define WORDS_BIGENDIAN 0
#endif
#ifndef HAVE_YIELD
#define HAVE_YIELD 0
#endif
</SNIP>
