What about this then:

#ifndef HAVE_STRCASECMP
# ifdef HAVE_STRICMP
# define strcasecmp(x,y) stricmp(x,y)
# else
#  ifdef HAVE_STRCMPI
#  define strcasecmp(x,y) strcmpi(x,y)
#  else
#   /* no case insensitive function available */
#   define USE_OUR_OWN_STRCASECMP
#  endif
# endif

# ifdef USE_OUR_OWN_STRCASECMP
int strcasecmp(const char *first, const char *second) {
  while (*first && *second) {
    if (toupper((int)*first) != toupper((int)*second))       break;
    first++;
    second++;
  }
  return toupper((int)*first) - toupper((int)*second); }
# endif

#endif /* HAVE_STRCASECMP */

Yes. Well, if you stick the above stuff in a header file somewhere. I'll add the checks for stricmp() and strcmpi() to the configure script.
