| 63 | Some C compilers have problems with their optimizers, by default, $package |
| 64 | compiles with the -O flag to use the optimizer. Alternately, you might want |
| 65 | to use the symbolic debugger, which uses the -g flag (on traditional Unix |
| 66 | systems). Either flag can be specified here. To use neither flag, specify |
| 67 | the word "none". |

| 152 | Your C compiler may want other flags. For this question you should include |
| 153 | -I/whatever and -DWHATEVER flags and any other flags used by the C compiler, |
| 154 | but you should NOT include libraries or ld flags like -lwhatever. If you |
| 155 | want $package to honor its debug switch, you should include -DDEBUGGING here. |
| 156 | To use no flags, specify the word "none". |
| 157 | |

158 | Your C compiler might also need additional flags, such as -DJMPCLOBBER, |
| 159 | -DHIDEMYMALLOC or -DCRIPPLED_CC. |
