Hi, I have 3 questions:

1.  How does djgpp behave with respect to long doubles? Are they padded to
make the length 12 bytes? When they are stored, is the extra padding set to
any value or is it just garbage?

2. Is there a way to determine if my program is generating floating point
exceptions? I see an ieeefp.h header, but I can't find any documentation
anywhere.
The ideal would be to specify a call back function.

3. Perhaps I'm blind but I can't find a <limits> header and limits.h seems
to be
a C header with macros.

Thank you for your time,
Patrick
