Some C compilers have problems with their optimizers, by default, $package
compiles with the -O flag to use the optimizer. Alternately, you might want
to use the symbolic debugger, which uses the -g flag (on traditional Unix
systems). Either flag can be specified here. To use neither flag, specify
the word "none".

Your C compiler may want other flags. For this question you should include
-I/whatever and -DWHATEVER flags and any other flags used by the C compiler,
but you should NOT include libraries or ld flags like -lwhatever. If you
want $package to honor its debug switch, you should include -DDEBUGGING here.
To use no flags, specify the word "none".
Your C compiler might also need additional flags, such as -DJMPCLOBBER,
-DHIDEMYMALLOC or -DCRIPPLED_CC.
