This fixes failures of icc without -mieee-fp on test-{ceil,floor}f2.c.
However, it does

I was about to fix strtod to use copysign to work around the icc
bug; the first step is to strengthen the test to prove that it
will work with icc. I've tested that

With optimization, ICC 10.0 mis-compiles 'cond ? -val : val' such
that a val of 0.0 doesn't result in -0.0.
* lib/strtod.c (minus_zero): Define to working value.
(strtod): Use it to avoid icc bug.

This fixes strtod under icc with optimization, which had been silent
* MODULES.html.sh: For compiler warnings, use name
`ansic_ext_compwarn' since `ansic_ext_misc' is already taken.
