| 5 | * macros defined with -Dname[=value] |
| 6 | * macros undefined with -Uname |
| 7 | * include search directories specified with -Idir |
| 8 | * libraries specified with -lllib |
| 9 | * library search directories specified with -Ldir |
| 10 | * compile handled by 'cc' (or similar) executable with -c option: |
| 11 | compiles .c to .o |
| 12 | * link static library handled by 'ar' command (possibly with 'ranlib') |
| 13 | * link shared library handled by 'cc -shared' |
