Correct.  The mere use of a GPLed program (like gcc) to transform text
does not infect the output text with the GPL, *unless* the program copies
substantial portions of itself into the output.  Bison does so, and for
years parser code created by Bison had to be GPLed, but then the FSF
changed the license on the parser skeleton so that this was no longer so.
