Read the documentation.  Start info and find libc.a.  If you haven't got
the info program, then go to wherever you got DJGPP and download
txi360b.zip.  
libc.a lists the standard C functions.  If these are supported by gcc
under Linux (which DJGPP is ported from) then they should be there, but
some functions aren't implemented (such as pipe() or fork()) because
they can't be done under DOS.  If you want to use pipes, then download
Linux, or buy Win95 or NT.

Hope this helps,
Barry Rodewald.
