Re: Error while building GCC 4.5 (MinGW)

Thanks for the prompt reply and suggestions.
I checked the config.log as per your suggestion.

>>Your file should have an error here.

Please check the following relevant information present in the config.log 
as follows:

configure:5690: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/.  See also
http://gcc.gnu.org/install/prerequisites.html for additional info.  If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files.  They may be located in separate packages.
================================= config.log ==========================

The mingw toolchain was successfully built with earlier 
versions(gcc-4.5-20091105).
However, the above problem is faced after introduction of "MPC" libraries.

Please let me know if there are any particular steps to be followed to build 
mingw toolchain with mpc libraries.

Brew
