[21.0b63] make-face-bold is broken under CYGWIN+X...
... and I don't know how to fix it.
In faces.el around 975 or so, there is the following code,
;; handle X specific entries
(when (featurep 'x)
(frob-face-property face 'font 'x-make-font-bold locale))
(when (featurep 'mswindows)
(frob-face-property face 'font 'mswindows-make-font-bold locale))
When evaluating,
(copy-face 'default 'bold)
(make-face-bold 'bold 'global)
under CYGWIN+X, the following appears to happen,
o First, x-make-font-bold is called and correctly derives the bold version of
the default font. The face is then changed ('global) to this font.
o Second, mswindows-make-font-bold is called and derives a Windows font name
of the existing font name. The face is then changed ('global) to the Windows
font!
The final effect is that the font-name is set to a Windows font name for
display under X.
If someone could suggest a way to fix this, I'll submit the patches....
