NOTE:
I cannot get the vanilla getopt code to work (i.e. compile only what
is needed and not duplicate symbols found in the standard library)
on all the platforms that FLAC supports. In particular the gating
of code with the ELIDE_CODE #define is not accurate enough on systems
that are POSIX but not glibc. If someone has a patch that works on
GNU/Linux, Darwin, AND Solaris please submit it on the project page:

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