Warning color is brown; depends on the fact that Windows console mismaps brown to yellow

### Describe the bug

Warnings are expected to be yellow, but the ANSI escape sequence is for brown

Too awhile to notice because Windows has had for decades a mismapping where brown turns into yellow. But when you try it without Windows anywhere on the stack, the brown appears.

### Steps to reproduce

Have a project that has build warnings

Use lxterminal

Build the project

### Expected behavior

Warnings are yellow

### Actual behavior

Warnings are brown

### Is this a regression?

Don't think so

### Are there any workarounds?

I suppose I could use the tuner to turn the brown to yellow and mess up everybody else. But that is problematic for its own reasons.
