With this change, it's possible to make the libcxx std module work on mingw-w64 (although that requires a few fixes to those headers). In the regular cstdlib header, we have _LIBCPP_USING_IF_EXISTS flagged on every single reexported function (since a9c9183ca42629fa83cdda297d1d30c7bc1d7c91), but the modules seem to only have _LIBCPP_USING_IF_EXISTS set on a few individual functions. --- libcxx/modules/std.compat/cstdlib.inc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libcxx/modules/std.compat/cstdlib.inc b/libcxx/modules/std.compat/cstdlib.inc index a45a0a1caf8ba..4783cbf516239 100644 --- a/libcxx/modules/std.compat/cstdlib.inc +++ b/libcxx/modules/std.compat/cstdlib.inc @@ -25,7 +25,7 @@ export { using ::system; // [c.malloc], C library memory allocation - using ::aligned_alloc; + using ::aligned_alloc _LIBCPP_USING_IF_EXISTS; using ::calloc; using ::free; using ::malloc;
