#
# A bug in the offending versions (listed below) in main.c of NetBSD's
# m4 causes the build to loop forever allocating memory, and thus
# exhaust swap. Note that these versions were never in a release, but
# their existence did span most of the 5.99.x period and early
# netbsd-6 prereleases. Therefore, updating the broken system binary
# is the best course of action. Note that because TOOLS_PATH.m4 does
# not get defined early enough it does not seem to be possible to set
# PKG_FAIL_REASON.
