Compiling src/regex.c on a Tektronix 88k workstation results in these
warnings:

regex.c: In function re_search_2:
regex.c:1069: warning: argument passing between incompatible pointer types
regex.c:1069: warning: argument passing between incompatible pointer types
regex.c: In function re_match:
regex.c:1096: warning: argument passing between incompatible pointer types

The problem is that arguments of type (char *) are being passed to
parameters of type (unsigned char *).  A brute force fix is enclosed.
