Bug ID: 77277
Summary: -fdiagnostics-color=always disabled on _WIN32 for no
discernible reason
Product: gcc
Version: 5.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bruck.michael at googlemail dot com
Target Milestone: ---
diagnostic-color.c completely disables colorization for the _WIN32 platform.
However both the most recent Windows 10 cmd.exe terminal as well as existing
terminal emulators available on older Windows versions fully support the Escape
sequences generated by gcc.
Proposal:
-fdiagnostics-color=always should always emit color codes
If isatty() is not reliable or unavailable on _WIN32 then should_colorize()
could be short-circuited to return false on _WIN32.
