So use -Werror to upgrade warnings to errors. :->

GCC is not supposed to be a conformance checking tool,
unfortunately. However, I looked through the GCC documentation again, to
find a "-pedantic-errors" option.

I don't have the standard at hand, are there constructs that are
supposed to give warnings rather than errors? Or are all diagnostics
supposed to jam the build?

$ gcc -std=c89 -pedantic-errors -c try.c
try.c: In function `f':
try.c:3: error: pointer targets in initialization differ in signedness
try.c:4: error: pointer targets in initialization differ in signedness
try.c:5: error: pointer targets in initialization differ in signedness
try.c:6: error: pointer targets in assignment differ in signedness
