# Syntax Check Rules that we want to skip
#  * sc_immutable_NEWS: I can't make this test ever pass. If someone fixes it,
#  happy to remove it from here.
#  * sc_makefile_at_at_check: We seem to use it predominantly for setting
#  INTL_MACOSX_LIBS. Without access to a mac, there's no way to verify if it
#  supports usage of the $(VAR) notation
#  * sc_prohibit_atoi_atof: We use a lot of sscaf() to parse strings
#  * sc_prohibit_gnu_make_extensions: We use GNU make.
#  * sc_prohibit_strcmp: I don't like blind adherence to such rules. We try to
#  use strcmp correctly everywhere
