Can I use GCC without being forced to be GPL?

[jacob navia]

In a previous message, I have explained that I can't use the
bfd library under linux because it is a GPLed binary.

OK.

But can I use the gcc compiler with

system("gcc output.o");

to produce the executable?

If this usage of "gcc" makes my compiler system a
"derivative work" of gcc there is no sense by trying
to do a linux version at all.
