Subject: libcody: fix --enable-checking=... [PR 98311]
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4be6c4e2a4df5229ec4545e7244dfcdbf1f5bca1;p=gcc.git

libcody: fix --enable-checking=... [PR 98311]

The -enable-checking configure code in libcody didn't play well with
us.  This just uses libcpp's configurey for that piece.

	libcody/
	* configure.ac: Use libcpp's enable-checking code.
	* configure: Rebuilt.
