+Subject: [PATCH] gcc12 c++ compatibility re-tweak for rhel6: use function
+ pointer instead of lambdas instead of ptr_fun<>
+
+Saving 2 lines in ltrim/rtrim is probably not a good reason to drop
+compatibility with the RHEL6 system compiler.  Actually declaring a
+named function and passing the function pointer is compatible with
+everything.
+
+Upstream-Status: Backport [https://sourceware.org/git/?p=systemtap.git;a=commit;h=f199d1982ef8a6c6d5c06c082d057b8793bcc6aa]
