If we can get you up and going by modifying _your_ files, then we can
work on integrating the changes where they really belong :-)

File src/system.h does the include of string.h (or strings.h, as
appropriate).  A workaround for declaring strcasecmp and strncasecmp
would be to #ifdef their declarations, i.e.

--- system.h	9 Dec 2003 00:07:50 -0000	1.21
+++ system.h	11 Dec 2003 21:57:21 -0000
