# hacks to deal with obsolete stuff

# The following conditional statement appends "-std=gnu99" to CFLAGS when the
# compiler does not define __STDC_VERSION__.  The idea is that many older
# compilers are able to compile standard C when given that option.
# This hack seems to work for all versions of gcc, clang and icc.
