You might need to switch on -Wall or (more likely) -Wextra.

Not easily. Here is one example warning, amongst many:

../../trunk.git/zlib/uncompr.c:86:13: warning: a function declaration without a
prototype is deprecated in all versions of C and is not supported in C2x
[-Wdeprecated-non-prototype]

As I say, pattern /zlib/.*-Wdeprecated-non-prototype would probably work.
