Just an FYI but we only really officially support compilation through MSYS2
on windows which comes with tput anyway.
That stackoverflow link is for a separate standalone git shell which either
runs in a cut down msys shell or the native win32 command
prompt/powershell. configure cant be run from a standard win32 prompt in
the first place so supporting colored error codes within it is rather moot.
So this patch isnt actually needed as the existing tput code works within
msys2 already.
