The problem is mainly with assembly functions in the library, not with 
functions written in C.

I suggest to look the related discussions held on the djgpp-workers 
mailing list a few months ago.  You should be able to find those 
discussions via the www.delorie.com/djgpp/mail-archives/ page.
If you have ideas how to solve the problems raised in those discussions, 
please post them to djgpp-workers AT delorie DOT com.

Thanks.
