Currently, a simple
$ make
errors out because we compile with -Werror by default, turning all
warnings into errors. Although no warnings are emitted by our code
itself, two kinds of warnings are emitted by perl.h (perl 5.18.0):
-Wundef and -Wswitch-default
Use #pragma statements to squelch exactly those warnings, and get perf
to compile-pass by default.
