The reason of this is because PATH_MAX is not guaranteed to be defined on all platforms and Hurd doesn't define it. So either we need to support arbitrary long file path or we need to define own maximum path length. The rule here would be: - If it's not big trouble to support arbitrary long paths (i.e. in ghost by using std::string instead of char*) then arbitrary long path shall be implemented. - For other cases to use PATH_MAX please include BLI_fileops.h which takes care of making sure PATH_MAX is defined. Additional change: get rid of own changes made yesterday which were supposed to make storage.c work fine in cases PATH_MAX is not define, but on the second though it lead to unneeded complication of the code. Thanks Campbell for review!
