WARNING: gsl/gsl_sf_bessel.h: accepted by the compiler

[Dr. David Kirkby]

I keep getting this message if I use Sun's compiler (cc: Sun WorkShop
6 update 2 C 5.3 2001/05/15) on my Sun Ultra 80 with Solaris 9. I've
set the environment variable CC to cc. If the CC variable is not set,
then gcc is found and the bug does not appear. It might be a problem
with my coding of configure.in, but since the configure script
requests it is sent to address@hidden, I am doing this.

I'm not quite sure how a header file can be usable, but not present!!

If this email is not clear due to line wrapping, download version 1.20
of the configure.in script from:

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/atlc/sources/configure.in
