Just add a configure.in test for the presence of ieeefp.h, and then include
ieeefp.h if HAVE_IEEEFP in the files which use finite(). You don't need to
apologise for using Solaris :-). It's a matter of 
        AC_CHECK_HEADERS(ieeefp.h)
        (check that autoheader really includes a HAVE_IEEEFP variable then),
and then #ifdef HAVE_IEEEFP (_H ?), do the right thing (it can't hurt to
include both ieeefp.h and math.h on platform which have both but have
finite() in math.h, anyway)
