PR# 4654 Precompiled directory name containing space cannot be used

Attempting to compile a project that uses a precompiled library fails if the path to the precompiled library contains a space.

There seems to be no workaround other than to place the precompiled library in a directory that has no spaces n its path.

For example, this fails during freezing:

	precompiled ("C:\Eiffel\Office\Project excel2003_vision2")

Preparing C compilation...

NMAKE : fatal error U1073: don't know how to make 'C:\Eiffel\Office\Project'
Stop.


I tried adding escaped quotes, but this failed immediately:

	precompiled ("%"C:\Eiffel\Office\Project excel2003_vision2%"")

Error code: VD42
Lace error: precompiled directory/file is unreadable.
What to do: make sure that the directory/file exists and that appropriate
  permissions are set ("read" for files, "read/execute" for directories).

Directory: "C:\Eiffel\Office\Project excel2003_vision2"
