  As Jonathan suggested.

Tested x86_64-pc-linux-gnu, applying to trunk.

-- 8< --

The contracts implementation was using strchrnul, which is a glibc
extension, so bootstrap broke on non-glibc targets.  Use C89 strcspn
instead.

	PR c++/107781

gcc/cp/ChangeLog:

	* contracts.cc (role_name_equal): Use strcspn instead
	of strchrnul.
