I just tried the same example on 6.4beta4, with linux2.0.36pre
something, glibc and egcs1.1. (It compiled fine, for what it's
worth.)

I also get this erroneous behaviour:

postgres=> select cash_mul_flt8('$1', '123.77');
cash_mul_flt8
-------------
$123.76
(1 row)

and

postgres=> select cash_mul_flt8('$1', '123.99');
cash_mul_flt8
-------------
$123.98
(1 row)

This may be sense from a numerical analysis point of view, but it
suggests there's a problem somewhere: this is surely behaving in a
surprising way.
