The philosophy is that the gnulib modules should be simple to use. This means
that the header files can be #included unconditionally, in any order. Any
#ifs belong in our header.

Then the strcase.h would look like this:

   #if !HAVE_STRCASECMP || !HAVE_STRNCASECMP
   extern int strcasecmp(...);
   extern int strncasecmp(...);
   #endif

But when used on AIX 4.3.2 now we would get "undeclared function" errors/
warnings. After fixing this, it would look like

   #if HAVE_STRCASECMP && HAVE_STRNCASECMP
   # if HAVE_STRINGS_H
   #  include <strings.h>
   # endif
   #else
   extern int strcasecmp(...);
   extern int strncasecmp(...);
   #endif

I don't see the point of this added complexity. The thing works fine as is.
