You can get the source code from git using this command:
git clone https://git.xiph.org/opus.git
Alternatively, this is the Git version of that fixed_c6x.h file:
https://git.xiph.org/?p=opus.git;a=blob_plain;f=celt/fixed_c6x.h

Actually, it seems like that #if 0 doesn't even have a matching #endif

Let me know if/when it works. At that point it will be worth including
in the normal distribution.
