The cygwin path and the jdk path exist. The rest do not. As for the added paths: C:\\ProgramData\\chocolatey\\bin; <= does not exist C:\\msys64; <= does not exist C:\\msys; <= does not exist C:\\cygwin64\\bin; <= does not exist C:\\cygwin\\bin; <= exists C:/Program Files\\Java\\jdk1.8.0_172\\bin; <= exists With the exception of the jdk, the remaining paths are "newly added" in 3.0.5 when compared directly to 3.0.4. In the github issue, there is a fuller description of the local environment and ENV['PATH']: https://github.com/SCons/scons/issues/3336 I still don't understand (yet) why the JDK is added to the ENV[PATH] when running scons. An msvc compile after running vcvarsall.bat from a command line console does not add the JDK to the system path. I am manually adding the mingw-w64 binary to the path using AppendENVPath() to produce a mingw-w64 compatible import library from a msvc compiled DLL. The location of my mingw-w64 installation is not one of the paths SCons is silently adding. By silently adding the cygwin folder, generating a 64-bit import library from a 64-bit DLL compiled on a 32-bit platform fails (i.e., evidently the cygwin dlltool.exe does not support this or is not configured correctly when run in this context). My expectation is that the ENV[PATH] would contain only what's necessary for the MSVC compiler tools. Perhaps, my expectation is misguided.
