Greetings !

I recently (yesterday) switched to V2, because I was having
lots of problems dealing with hardware interrupts with V1.12.

I had to rewrite some of my code to adapt it, but it all compiles
fine now. The linking is the problem. I get the following output
when running make :

gcc -I/include -I. -O -g -Wall -o chaos interrup.o chaos.o csystem.o moonbeam.o vector.o
  -L/lib -L. -lgraph -lgrx -liostream -lm -lgpp -lpc

make.exe: *** [chaos] Error 1

The references to _iob and _ctype_ are in the libgrx code. Am I missing
something obvious here, or what ?

Any help/suggestions would be greatly appreciated !
