Comment (by barracuda156):

 Replying to [comment:7 evanmiller]:
 > The PPC assembler code included with the Boost {{{context}}} module has
 a few problems:
 >
 > * Its comments are prefixed with # instead of ;
 > * The exit function is suffixed with @plt, which confuses the assembler
 > * The {{{addi}}} instruction does not accept a 32-bit value

 pass so I punted on it.

 Just in case, for now I disabled `context` and `coroutine` in Boost for
 PPC, so every version should build. I will see if assembler can be fixed
 though. `context` is needed for some dependents to build.
