Anybody know a quick fix for this?

Turns out, it's a messy situation related to the makefiles. :-(

The required -Wnarrowing flag is already specified for gcc-based host
compilers; however, the makefile uses an unreliable string matching of
the compiler's --version output to detect gcc-based compilers.
Unfortunately, my distro (Debian) uses a custom gcc build that, for
whatever reason, doesn't include the string "gcc" in the output of
--version, so the makefile fails to detect gcc and doesn't include the
needed flag.

Is there a more reliable way to detect gcc-based compilers other than
string-matching of --version?  Perhaps a small utility program that uses
#ifdef __GNUC__ as a far more reliable compiler detection method?

it is not more reliable. other compilers may define that if they 
are trying to "mimic" gcc for some reason. i'd say "spam your 
distributive maintainers to fix their bug".
