That is not entirely correct for the component Deborah asked about.

Deborah asked about libgcc, which is the basic underlying runtime
support necessary to use GCC.

libgcc's license is what is typically known as "GPL + libgcc exception":

/* More subroutines needed by GCC output code on some machines.  */
/* Compile this one with gcc.  */
/* Copyright (C) 1989, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999,
