This is a trivial test program which may be useful to people who are
porting the GCC or G++ compilers to a new system.  The intent here is
merely to check that all floating-point operations have been provided
by the port. (Note that I say ``provided'' rather than ``implemented''.)

To use this file, simply compile it (with GCC or G++) and then try to
link it in the normal way (also using GCC or G++ respectively).  If
all of the floating -point operations (including conversions) have
been provided, then this file will link without incident.  If however
one or more of the primitive floating-point operations have not been
properly provided, you will get link-time errors indicating which
floating-point operations are unavailable.

This file will typically be used when porting the GNU compilers to
some system which lacks floating-point hardware, and for which
software emulation routines (for FP ops) are needed in order to
complete the port.
