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 http://sourceforge.net/projects/flac
11 In the meantime I have munged the global symbols and remove gates
12 around code, while at the same time trying to touch the original as
