The latest snapshot of GMP seems to have worked. Now I have hit a
problem with MPFR:
configure: error: libmpfr not found or uses a different ABI
(including static vs shared).
I found this in the FAQ for MPFR,
http://www.mpfr.org/faq.html#no_libgmp, but I'm not sure how GCC handles
this. When I put the MPFR code into gcc with the command "mv
$HOME/mpfr-3.1.2 $HOME/gcc-4.6.3/mpfr" how does GCC detect the library.
Do I need to specify it in my LD_LIBRARY_PATH of edit C_FLAGS with -I -L
and -l flags?
