gcc-you can use this code to learn something about gcc, and inquire further into linux,

# We need to use -fPIC when we are using gcc to compile the routines in
# crtstuff.c.  This is only really needed when we are going to use gcc/g++
# to produce a shared library, but since we don't know ahead of time when
# we will be doing that, we just always use -fPIC when compiling the
# routines in crtstuff.c.  Likewise for libgcc2.c.   This is less painful
# than multilibbing everything with PIC and PIC-not variants.

# The pushl in CTOR initialization interferes with frame pointer elimination.
