Minix editline v0.1.3

=====================

Fix another build warning for Arm cross-gcc, which actually was v4.1.2
This time getpid() was missing unistd.h, but kill() was also missing 
signal.h.  Added test for signal.h, but left out unistd.h since we
already define SYS_UNIX -- which we should really check for instead...

The rest are cosmetic prototype or automake/autoconf fixes.
