commit 6782d9991c942042c9a959b57355b4bbce5cb314

external/firebird: Make GCC check work for Clang, too
Randomly approximate that HAVE_GXX_FNO_SIZED_DEALLOCATION also implies
support
for -fno-delete-null-pointer-checks, and hope that approximation matches the
various versions of GCC and Clang that are relevant for us.
