Convert a MSYS path list to absolute, Windows-native format.
Convert a MSYS path list to Windows-native format.
PATHLIST should be a colon-separated list of MSYS paths, which will be
written to the standard output after performing these transformations:
1. Discard empty paths.
2. Replace: '\' with '/', '//' with '/' and ':' with ';'.
3. Translate each path to absolute, Windows-native format.
3. Translate each path to Windows-native format.
Paths starting with '%emacs_dir%' will be passed verbatim to the
standard output.
Relative paths or paths starting with '%emacs_dir%' will be passed
verbatim to the standard output.
Each non existing path will be translated by looking for its deepest
existing directory, which will be translated and the remainder
Each non existing absolute path will be translated by looking for its
deepest existing directory, which will be translated and the remainder
appended.
