And there lies the problem. cygwin32 does not use the GNU libc library
(if they did, they would not be able to require people to buy a license
from them to keep from releasing their source code). Instead, it uses
"newlib," with the source for the functions in question

Looking at the code, l is long ints, L is for long doubles, ll is
supposed to be for long long ints (QUADINTs), and q is also for long
long ints. If things are not working like this, you'll need to take a
look at cdk/src/newlib/stdio/vfprintf.c to attempt to find the
problem.
