Hi Phil:

Thanks for the above detailed information which contradicted some of
my assumptions (natch).

However, I am frankly beginning to get cold feet about working much
further on this topic since from my Linux test of the case where
external libraries have blanks and hyphens in their installation
prefixes, there are a huge bunch of issues we would have to deal with
before that case worked, i.e., it would be a lot of work for little
real gain.

For example, my understanding is Windows installers typically give you
a choice of any installation prefix you want.  So wouldn't it be a lot
easier to ask our Windows users to be careful of that choice, i.e.,
pick installation prefixes without blanks or hyphens?  For example,
MSYS2 allows users to choose any installation prefix they like.  And
I think they even recommend not choosing an installation prefix with
spaces because of all the trouble that causes with free software.
