That's great work, and I can confirm that it is the same in my 
environment. Our makefiles start the following:

  * Several cygwin utilities (e.g. cygpath, cut, sed, etc.)
  * Linux cross-compilers/linkers that are cygwin programmes
  * Windows native compilers/linkers (not cygwin)
  * HPE Nonstop cross-compilers/linkers (not cygwin)

So what you've found is consistent with the issue that we're getting.
