I've lots and lots of apps and their configurations. I am not thinking about
transfering right now.

So I tried uninstalling the old libmpfr and using the command line parameters:

--with-mpfr=pathname
--with-mpfr-include=pathname
--with-mpfr-lib=pathname

Still gcc doesn't see the new lib. Seems like gcc is using the old lib 
location which doesn't have mpfr_remainder() function. That creates 
the previous errors from my first post.


Changes from versions 2.2.* to version 2.3.0(from mpfr homepage)
   ......
    * New functions mpfr_j0, mpfr_j1, mpfr_jn, mpfr_y0, mpfr_y1,                
       mpfr_yn ,mpfr_lgamma, mpfr_remainder, mpfr_remquo, mpfr_fms,             
       mpfr_signbit, mpfr_setsign, mpfr_copysign,       mpfr_get_patches.
    * Functions mpfr_sin, mpfr_cos and mpfr_sin_cos improved (argument 
       reduction).
    ......


i think gcc needs to respect the location and CL parameters that refer to new 
lib. Is  there anyway to force the  compilation process to recognize the new 
path without creating symbolic link (even if it means modifying the source)? I 
can provide assistance regarding this bug. output from config.log during 
`make`:
