# FILTER_MACROS
# -------------
# The test `syntax.m4' tries to run all the macros of Autoconf to check
# for syntax problems, etc.  Not all the macros can be run without argument,
# and some are already tested elsewhere.  EGREP_EXCLUDE must filter out
# the macros we don't want to test in syntax.m4.
#
# - AC_CHECK decl, file, func, header, member, prog, sizeof, type
#   Performed in the semantics tests.
# - AC_CONFIG
#   They fail when the source does not exist.
# - AC_INIT
#   AC_INIT includes all the AC_INIT macros.  Note that there is an
#   infinite m4 recursion if AC_INIT it used twice.
# - AC_PROG_(CC|CXX|F77)_(GNU|WORKS)
#   are used in AC_PROG_CC etc.
# - AC_PATH_PROGS?
#   They produce `= val' because $1, the variable used to store the result,
#   is empty.
# - AC_TRY
#   Used in many places.
# - _AC_
#   Internal macros are used elsewhere.
#
# Multiple `-e' to egrep are not portable, so join all the patterns together.
# We use the fact that automake will replace all the `\\\n' with ` '.
