I don't know anything about EMX, but your code is certainly problematic.
A C compiler is free to store strings constants like "3.4 4.1" in 
read-only memory [hence their name].  Since strtok will try to write 
into that memory, an access violation should be expected.

To be portable, you need to copy that string either into an automatic variable
or copy it into some malloc'ed memory.

Under UNIX, you can pass gcc the option -fwritable-strings to tell gcc you
really want to be able to write into string constants.  Perhaps this would
solve your problem with EMX.
