It's also possible that the compiler is running in a "warnings are
errors" mode.  Hack the Makefile (or equivalent) at your own peril.

One of the annoying things about warnings is that they're not standard,
so squelching them under one compiler makes another compiler (or a
different version of the same compiler) whine.  IIRC, a compliant C
compiler can issue a warning for anything it wants, including "this
variable name contains too many vowels" or "this is a computer, and
today may be Tuesday."

In many ways, the engineering pieces of software engineering remain in
their infancy.  *sigh*
