Hello Nate,

please use https://github.com/olk/boost.context - I don't get compiler 
errors with this source for 32bit/64bit Linux on x86.

The errors above point to some problems with boost.move. Which version 
did you use? Could you test the lib with the sources from github?

Unfortunately MinGW is not supported yet - this would require to port 
the assembler code written for MASM to GAS. Maybe in the near future I 
find time doing this (or if you want you can do -> requires only to port 
the assembler syntax)..

best regards,
Oliver
