Subject: libstdc++: Do not use dirent::d_type unconditionally
X-Git-Tag: releases/gcc-11.3.0~123
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=583267dc1e45a32217ed6e8ea59df9f46ec4bce6;p=thirdparty%2Fgcc.git

libstdc++: Do not use dirent::d_type unconditionally

These new tests should not use the d_type member unless it's actually
present on the OS.

libstdc++-v3/ChangeLog:

	* testsuite/27_io/filesystem/iterators/error_reporting.cc: Use
	autoconf macro to check whether d_type is present.
	* testsuite/experimental/filesystem/iterators/error_reporting.cc:
	Likewise.

(cherry picked from commit d98668eb06f532b2dbe0c721fa1b9ed6e643df27)
