Even though you *used* GCC to build the program, gcc *itself* is in no
way present in the program you distribute. There's no portion of gcc
source code or binary in your application. Thus, your program does not
inherit the licensing from the gcc GPL license.

The only think that gets bundled is the C library. And the C library
(glibc) is covered by the LGPL, which specifically allows for that case
(i.e. distributing a program that is linked with a GPL software, without
 placing the GPL strictures on the program itself).

The same thing would apply to a C grammar parser that was generated
by bison (the GPL parser generation tool). Using bison to generate your
C source does not require you to put said source under the GPL: bison
is not included in your program, only its output (hmmm, is the library
required for bison LGPL? I think so, but can't remember)
