This patch cures the testsuite failure of bfin/20090914-3.c, which
currently FAILs on bfin-elf with "(test for excess errors)" due to:
20090914-3.c:3:1: warning: return type defaults to 'int' [-Wimplicit-int]
which is obviously not what this code was intended to test.  Fixed by
turning the code into a function returning the final "fract32" result,
as simply specifying an "int" return type for main, results in the
entire function being optimized away, as the result is unused.

Checked-in as obvious.
