-mno-fancy-math-387 disables generation of fsqrt, fsin, and several other
instructions. It was needed long ago when FreeBSD supported FPUless 80386 and
80486 systems via a partial in-kernel emulator that couldn't cope with these
instructions. Support for FPUless x86 machines was dropped many years ago, and
the emulator is gone, so -mfancy-math-387 should be the default for FreeBSD.

Thanks for reporting this, David, and I'm sorry that nobody analyzed
this before.
I cannot find a bit like this in the GCC sources and a bit of digging
reveals
Revision 1.35:
Thu Mar 23 10:18:25 2000 UTC (10 years, 10 months ago) by obrien
Branches: MAIN
Changes since revision 1.34: +545 -382 lines
Clean up the FreeBSD configuration files -- includes removing the usage
of svr4.h on the i386, and moving all the shared arch neutral bits into
the FreeBSD general config header.
http://www.freebsd.org/cgi/cvsweb.cgi/src/contrib/gcc/config/i386/freebsd.h.diff?r1=1.34;r2=1.35;f=h
as the point where this was introduced into the FreeBSD system compiler.
I believe there is no action to be taken on the upstream GCC side.
If I am wrong or missing something, please let me know and I'll do my
best to help address this!
