I think we should use #pragma GCC poison in $cih_test_c, like this:

diff --git a/scripts/check-installed-headers.sh b/scripts/check-installed-headers.sh
index 8e7beffd82..f9e39eb995 100644
--- a/scripts/check-installed-headers.sh
+++ b/scripts/check-installed-headers.sh

+#pragma GCC poison ushort
+#pragma GCC poison ulong
+#pragma GCC poison uint

 /* The library mode is selected here rather than on the command line to
    ensure that this selection wins. */
 $expanded_lib_mode

And then get rid of the grep.

Thanks,
Florian
