Exactly my situation ... :-)

I was wondering whether it was possible to cut out the middle-man, so to
speak (i.e. HAVE_GSL_INLINE) and simply rewrite the

    AC_CHECK_HEADER([gsl/gsl_inline.h],[AC_DEFINE([HAVE_GSL_INLINE],
     [1],[Define if gsl/gsl_inline.h header exists])])

to do something other than AC_DEFINE([HAVE_GSL_INLINE]) -- i.e. to
create a header that either has

    #include <gsl/gsl_inline.h>

or

    #define INLINE_FUN extern inline

... but in any case, the proposed solution seems to work, thank you very
much for the kind assistance! :-)

Best wishes,
