Re: Problems compiling the GCC 4.3.5

Thanks for the hints. I replaced the 3.0.0 version of mpfr with the 2.4 
versoin. Now the compilation process runs quite a while (subjectively 
about an hour) but finally ends again with an error message. The one I 
get is this one

ld: warning: directory 
'/Users/toom/Downloads/gcc-4.3.5-base/obj-gcc-4.3.5/./gmp/_libs' 
following -L not found
ld: warning: directory

following -L not found
