This sounds fine to me.

This sounds odd to me. I suppose there's a large number of systems out there
now that support the SVR4 dlopen() interface, and that's wonderful for them.
Having recently ported libltdl to IBM z/OS I'm wary of anything that assumes
that dlopen is universal though. I know it's now supported on recent versions
of AIX too, but having managed to cause a kernel panic the first time I used
that (way back on AIX 4.2.1) I've never trusted it, and always build for the
native AIX shared library mechanism instead.

I don't understand how being allowed to use ANSI function prototypes means
that libltdl can get smaller. ??
