mingwex/gdtoa/ulp.c: Update the gdtoa library to match the netlib.org
sources as of Apr. 20, 2009. Update further to match the sources in
the mingw-w64 tree as of June 28, 2009, by removing IBM, CRAY and VAX
code, removing KR_headers, ANSI, Void and Char ifdefs, renaming the
double/ulong union from U to dbl_union for better grepping and white-
space tidy-ups.
