New description:

 Building xscorch fails to build on Mac OS 10.6. This is the error I saw in
 the log:

 {{{
 :info:build clang: error: unknown argument: '-fthread-jumps'
 }}}

 Here is a description of the option for GCC 3.4 found here:
 https://gcc.gnu.org/onlinedocs/gcc-3.4.6/gcc/Optimize-Options.html:

 {{{
 -fthread-jumps
     Perform optimizations where we check to see if a jump branches to a
 location where another comparison subsumed by the first is found. If so,
 the first branch is redirected to either the destination of the second
 branch or a point immediately following it, depending on whether the
 condition is known to be true or false.

     Enabled at levels -O, -O2, -O3, -Os.
 }}}

 I could not find a reference to `-fthread-jumps` working with clang.

 This issue talks about how clang does not recognize a lot of flags
 (fthread-jumps included): https://github.com/pcsx2/pcsx2/issues/295

 My guess is xscorch is meant to be built with GCC instead of Clang.
