   There is a bug in the DJGPP v2 library: it defines `stdprn' as using file 
   handle 3 and `stdaux' as using handle 4, whereas it should be the other 
   way around.  So when you fprintf to stdprn, it actually tries to write to 
   the COM1 port, with the obvious results.

   To correct this, compile the files `stdprn.c' and `stdaux.c' below and 
   put them into your C library, like this:

	   gcc -Wall -O3 -c stdprn.c
	   gcc -Wall -O3 -c stdaux.c
	   ar rvs c:/djgpp/lib/libc.a stdprn.o stdaux.o
	   ranlib c:/djgpp/lib/libc.a

   and print happily ever after by writing to stdprn.

   Opening "PRN" or "LPT1" works for me.  For instance the following program 
   really prints:

Thanks Eli.  I'll try this soonest and feed back.
