#-------------------------------------------------------------------------------
# pycparser: using_gcc_E_libc.py
#
# Similar to the using_cpp_libc.py example, but uses 'gcc -E' instead
# of 'cpp'. The same can be achieved with Clang instead of gcc. If you have
# Clang installed, simply replace 'gcc' with 'clang' here.
