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.

The gdtoa code here is based on David M. Gay's original
|
|
gdtoa source at http://www.netlib.org/fp/ from April 20,
|
|
2009. The major changes between the original source and
|
|
the mingw port here include:
|
|
|
|
* IBM, CRAY and VAX code removed.
|
|
* KR_headers, ANSI, Void and Char ifdefs are removed.
|
|
* gdtoa symbols are prepended with "__".
|
|
* g_xfmt() uses __fpclassifyl() instead of interpreting
|
|
the flags bit-wise.
|
|
* lo0bits() and hi0bits() of misc.c replaced by wrappers
|
|
to gcc's __builtin_clz()
|
|
* The double/ulong union renamed from U to dbl_union
|
|
(grep'ped better..)
|
|
* A few compiler warning fixes here and there.
|
|
* A few other insignificant changes (if any..)
|
|
|
|
MinGW specific compile-time definitions are at the top of
|
|
gdtoaimp.h and gdtoa.h headers.
