[New-bugs-announce] [issue41027] get_version() fails to return gcc version for gcc-7

[mbarbera]

New submission from mbarbera <matteo.barbera97 at gmail.com>:

In Lib/distutils/cygwincompiler.py, get_version() tries to parse the output of shell commands to check for the gcc version. gcc-7 has changed the behavior of the flag -dumpversion to only show the major version number. This prevents the regex string RE_VERSION from parsing the version number from the shell output.

The issue was encountered when trying to install a third-party module to python3.6 on Ubuntu 18.04
