Two small changes, one because of case sensitivity, and one because you
forgot the fl_push_clip() call (the Linux version outputs "fl_pop_clip:
clip stack underflow!"). Other than that, it works on Ubuntu 9.04, no
differences to the windows version visible.
Here's the patch:

... unless you wanted to remove fl_pop_clip() as well ;-)
And, needless to say, this should be changed for Windows and Mac, too.
