no, Win32 make - i noticed while adapting the LibreOffice build system from Cygwin make to Win32 make a couple years ago (which gave a large speed improvement, see [1] for details) that some commands that used to work before failed with Win32 make because the command lines were truncated. > And yes, the native Windows build of Make supports command lines up to > 32K bytes, except when it invokes cmd.exe, which itself is limited to > 4K bytes. i think i looked at it in a debugger and saw that the command line was indeed passed to CreateProcess un-truncated but i forget the details, it was some years ago, i don't think i found out where exactly the truncation happened.
