------- Additional Comments From dannysmith at users dot sourceforge dot net 2005-07-31 00:56 ------- This may be the problem:
In mk-kinds-h.sh: case $largest_ctype in float) echo "#define GFC_REAL_LARGEST_FORMAT \"\"" ;; double) echo "#define GFC_REAL_LARGEST_FORMAT \"l\"" ;; "long double") echo "#define GFC_REAL_LARGEST_FORMAT \"L\"" ;; *) echo "$0: Unknown type" >&2 ; exit 1 ;; esac Although mingw supports long double math, the native msvcrt.dll runtime printf family does not. The 'L' format specifier is ignored and passing long doubles to printf doesn't work at all--the values are interptreted as doubles. The same problem occurs in libstdc++ and the unsatisfacpory hack that mingw distros use is to cast long doubles to doubles before sending to snprintf.
