| 2 | NOTE: |
| 3 | I cannot get the vanilla getopt code to work (i.e. compile only what |
| 4 | is needed and not duplicate symbols found in the standard library) |
| 5 | on all the platforms that FLAC supports. In particular the gating |
| 6 | of code with the ELIDE_CODE #define is not accurate enough on systems |
| 7 | that are POSIX but not glibc. If someone has a patch that works on |
| 8 | GNU/Linux, Darwin, AND Solaris please submit it on the project page: |
| 9 | https://sourceforge.net/p/flac/patches/ |
| 10 | |
| 11 | In the meantime I have munged the global symbols and removed gates |
| 12 | around code, while at the same time trying to touch the original as |
| 13 | little as possible. |
