[PATCH]: fix for floating point arg passing on x86-Solaris



This supercedes my earlier patch for float/double promotion.
This patch affects only x86 Solaris.  Comment copied from one
of the half-dozen other files that define COERCE_FLOAT_TO_DOUBLE.

2000-05-12  Michael Snyder  <msnyder@falafel.cygnus.com>

        * config/i386/tm-i386sol2.h: Define COERCE_FLOAT_TO_DOUBLE.
