1The gdtoa code here is based on David M. Gay's original 2gdtoa source at http://www.netlib.org/fp/ from Sep. 27, 32010. The major changes between the original source and 4the mingw port here include: 5 6* IBM, CRAY and VAX code removed. 7* KR_headers, ANSI, Void and Char ifdefs are removed. 8* gdtoa symbols are prepended with "__". 9* g_xfmt() uses __fpclassifyl() instead of interpreting 10 the flags bit-wise. 11* lo0bits() and hi0bits() of misc.c replaced by wrappers 12 to gcc's __builtin_clz() 13* The double/ulong union renamed from U to dbl_union 14 (grep'ped better..) 15* A few compiler warning fixes here and there. 16* A few other insignificant changes (if any..) 17 18MinGW specific compile-time definitions are at the top of 19gdtoaimp.h and gdtoa.h headers. 20 21
