[tex-live] proto10.map and xdvipdfmx in revision 2381

     ttf2pk's configure apparently didn't use the  
    cached value, but came up with its own value (blank). 

I've checked in a new version of ttf2pk/configure and
freetype/freetype.ac which I believe fixes the problem.  Please try if
you can.

The bug was that freetype.ac, in the --with-system-freetype case, did
not ensure that $CPP was already defined; so it saved and restored an
empty value.  The other packages which use freetype (apparently) had
already defined $CPP, but ttf2pk did not.

Hope this will do it ...
