And what's the problem with it? (I haven't seen the original bug report from
Nelson Beebe.) GNU gettext 0.14.1 uses this module, and compiles fine on
AIX 4.3.2, which also has strcasecmp() and strncasecmp() defined in libc and
declared in <strings.h>.

Well, the documentation at
http://savannah.gnu.org/cgi-bin/viewcvs/gnulib/gnulib/MODULES.html?rev=HEAD&content-type=text/html#module%3Dstrcase
says that just

   #include "strcase.h"

should work, and for me it does.

I don't see why. The AIX <strings.h> declaration doesn't conflict with
gnulib's "strcase.h" declaration, therefore this declaration is irrelevant.
