# Configure flag notes:
#  1. Standard flags. See gcc.morph.
#  2. Disable searching /usr/local/include for headers
#  3. The pass 1 compiler needs to find the libraries we build in pass 2.
#     Include path must be set explicility, because it defaults to
#     $SYSROOT/usr/include rather than $SYSROOT/include.
#     FIXME: this flag is not present until GCC 4.6.3!
#  4. Disable stuff that doesn't work when building a cross compiler
#     without an existing libc, and generally try to keep this build as
#     simple as possible.
