* pinfo.h: Correctly set __SIGOFFSET. * path.cc (hash_path_name): Avoid calling library functions for simple copying of characters. * shortcut.c: Use WIN32_LEAN_AND_MEAN. * smallprint.c: Ditto. * environ.cc (getwinenv): Minor clarity fix. * localtime.c: No need to include windows.h * string.h: New file.
