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. |
