Re: xgcc unable to build libgcc under mingw

["Alexander Shabanov" <avshabanov at gmail dot com>]

Thank you very much, your advice works.

As a conclusion - in case somebody again will want compile gcc under MinGW:
1) create in your msys `local' directory folder `i686-pc-mingw32'
2) copy all(I copied all :)) content of msys' root directory to this
folder (of course, except `local' directory)
3) configure & make.

After `make install' you will have several gcc on your computer.
Compiled gcc compiler driver will have name `i686-pc-mingw32-gcc.exe'.
