Re: [feature/native-comp] breakage on build

[Eli Zaretskii]

I have a guess why it fails, based on this part of the trace:

  compiling to 
c:/msys64/home/Administrator/emacs-build/build/emacs-28.0.50-snapshot-feature_native-comp-windows/native-lisp/28.0.50-x86_64-w64-mingw32-3459bc949453c7833f94b407f8ee7c17/titdic-cnv-765ac3beca7090ba17f799d9600c18e6-a5dbcc84a969a94717512a079e1cc96a.eln

The name of that file is suspiciously close to the 260-byte limit of
file-name length that Win32 APIs support.  So my guess is that the
temporary file had a few more characters (like the 6 characters which
replace the XXXXXX, perhaps?), and that caused the failure.

Solution: use a directory with a shorter name (the above is really
excessive in its leading part, IMO).
