Allow compilation in directory with spaces

[marisn]

As of GRASS 6.5 it's not possible to configure and make GRASS if it's source is located in directory containing spaces in it's path.

Steps to reproduce:

make distclean
mv /path/to/my/grass/source "/path/with/spaces/to/grass source"
./configure && make

Configure part is easy but other Make system parts are more tricky.

The configure script is generated from configure.in by autoconf. You can't modify configure directly.

Beyond that, the portions of the configure script which you changed are inserted verbatim by autoconf, so the only way to fix this is to fix autoconf; there isn't anything that can be done within GRASS.

BTW, non-trivial patches should normally be added as attachments, rather than inserted into the body of the message.

I have now (well some weeks ago) quoted everything in configure.in and install-sh that could be quoted, but as Glynn explains there are parts of configure which are automatically added by autoconf, and unfortunately those bits are not all quoted.

closing as "wontfix", even though it is more accurately "cantfix". (without moving away from autoconf2.13, and to justify that I'd say we need a more compelling reason than this problem)
