Please don't make this issue more confusing than it already is by posting 
untested and unverified replies.  DJGPP doesn't come with GNU C library, 
its C library is free, so programs written in C don't have the above 
restriction.  Programs written in C++ and compiled with DJGPP *are* 
subject to these restrictions if they use classes from the libgpp.a 
library; if you only use classes from libiostream.a library, then again 
there are no restrictions.  For details see the DJGPP FAQ list (available 
as faq102.zip from the same place you get DJGPP), Chapter 19.
