 for upgraded compilers

Dear All

thanks for the reply

I have brought up the configure help pages of GNU.
While I had tried the inclusion of the --with they failed because I did 
not understand that I needed to be one directory above the lib and the 
include directories to use --with-mpfr=DIRECTORY option

Here below where I have explicity included the mpfr library and the 
include  headers all seems to be fixed. I have also tested the generic 
include and it too works.

I will continue with compilation make.
