New Revision: 265634

URL: http://llvm.org/viewvc/llvm-project?rev=265634&view=rev
Log:
Don't use PATH_MAX.

This is a SmallVector anyway, and so the exact size doesn't matter.

clang\lib\Frontend\ModuleDependencyCollector.cpp(83) : error C2065: 'PATH_MAX' 
: undeclared identifier
clang\lib\Frontend\ModuleDependencyCollector.cpp(83) : error C2975: 
'InternalLen' : invalid template argument for 'llvm::SmallString', expected 
compile-time constant expression
        llvm\include\llvm/ADT/SmallString.h(24) : see declaration of 
'InternalLen'
