Boost :

The title says it all: the Mac OS X system headers are inconsistent
about the minimum value of a wchar_t. The C++ <limits> header has it
right, but the definition of WCHAR_MIN in <cwchar>/<wchar.h> is wrong
(0). If there are no complains, I'm going to commit the following
patch. I don't believe this will affect CodeWarrior on the Mac, but I
can't test against it.
