> The #endif for the #ifdef Linux block to add the "get_current_prefix()"
> and the "file_prefix_arg()" functions to process.h was on the wrong
> line, leaving a stray "}" outside the block. Fix this and in the process
> (no pun intended) simplify the #ifdefs to just a non-Linux and a Linux
> block, removing one level of #ifdefs.
