expected unqualified-id before numeric constant #116

When cross-compiling on powerpc64le, gcc is unhappy about this line, stating:

     const unsigned CHAR_WIDTH = 1;

Sounds like this may be due to something else defining CHAR_WIDTH on this system, which does in fact exist within limits.h in my compiler toolchain. My guess is that this variable just needs to be renamed.

Manually renaming CHAR_WIDTH worked for me.
