Now, I have a patch, that checks for "original" CXXFLAGS being empty or not.
If empty, it will be unset after the tests.

This works fine, but prevents the user from setting CXXFLAGS to the empty string
in his own WILL.

Example:

        $ CXXFLAGS="" ./configure # will result in using default CXXFLAGS

                Same as:

        $ ./configure

This is unless anyone knows a tip to check if a variable is set or not using a 
bourne shell.
(ie: empty string counting as being set)
