Build of gcc-4.1

[Paul Thomas]

I have been trying to build gfortran, using mingw. With help from 
Francois-Xavier Coudert and much consumption of midnight oil(strange 
problems with the makefile associated with the check of m4 in the build of 
gmp/mpfr),  I have got as far as libgfortran and there the build fails 
because gcc does not produce executables.  gfortran and xgcc both produce 
code and object files.  The libgfortran build and the loading of programs 
compiled with xgcc fail for the lack of crt2.o.  This latter is found in 
/mingw.  None of the things that are obvious, to me at least, seem to 
resolve the loader's problem in finding it.  Any ideas any one?
