Tcl Source Code

When building with present cygwin, the cygwin version of rmdir and mkdir are used. This causes the following error, as the parameters are different:

/usr/bin/rmdir: `/S': Permission denied
/usr/bin/rmdir: `/Q': No such file or directory
/usr/bin/rmdir: `C:\\test\\fossil\\tk\\6a9bae5e-demo-dist-nmake\\win\\Release_AMD64_VC1944\\libtk.vfs\\tk_library\\demos': Directory not empty
NMAKE : fatal error U1077: "rmdir /S /Q "C:\test\fossil\tk\6a9bae5e-demo-dist-nmake\win\Release_AMD64_VC1944\libtk.vfs\tk_library\demos"": Rückgabe-Code "0x1"

This happened in this tk bug 6a9bae5e.

It must be fixed here, as the rules.vc of TCL is used also for Tk. A local copy is ignored, if TCL has one.

Csaba proposed the following fix:

1. makefile.vc includes rules-ext.vc, which in turn includes rules.vc.  The latter defines RMDIR and MKDIR as follows:

  RMDIR   = rmdir /S /Q
  ...
  MKDIR   = mkdir

This is dangerous, because rmdir and mkdir are not only Window (originally DOS) commands, but they are also present in cygwin and msys/mingw, being that these emulate a part of a Unix environment.  And the cygwin commands seem to have precedence over the commands of the same name of Windows. 

IMHO, the above definitions should be replaced with

  RMDIR   = rd /S /Q
  ...
  MKDIR   = md

This would be better because rd and md are not present in cygwin and msys/mingw, thus no command-related ambiguities could happen any longer.

THanks for all, Harald
