Current trunk, rev. 169888, fails to bootstrap on Cygwin with this error:
[...]
/tmp/gcc-4.6-r169888/libgcc/config/libbid/bid_decimal_globals.c:47:18:
fatal error: fenv.h: No such file or directory
compilation terminated.

usually I do weekly builds without any problem configuring with
$ gcc-4.6 -v
Using built-in specs.
