Could you make the check and the error message a bit more precise? For
example, CFLAGS="-O2 -fno-optimize-sibling-calls" should get through
(CFLAGS="-O1 -foptimize-sibling-calls" should not, but that can
probably be ignored). It'd also be nice if either the error message or
the comments in configure.in referred to this bug.
Kind regards,
Elias
