# in case we want to commit it. Other than that, version 2.59 is
# perfectly fine for our purposes, so people who want to modify
# this file just have to remember to set the AC_PREREQ argument
# to something that suits their needs.

# we don't want those default flags to be carried over into the
# rest of the build system since we have other means of controlling
# debugging symbol generation and optimization.
