 The "MinGW-target GCC on MinGW-host" seems to follow the old familiar
"use the stuff where it was started from" rules with the target headers :

BUT NOT with the target binutils and libraries :

install: /usr/local/lib/gcc-lib/i686-mingw32/4.1.2/

/usr/local/i686-mingw32/lib/i686-mingw32/4.1.2/;
/usr/local/i686-mingw32/lib/

This thing is a serious BUG !   The directory :

  
e:/usr/local/bin/../lib/gcc-lib/i686-mingw32/4.1.2/../../../../i686-mingw32/bin

should be there in 'programs: =' and the :

   
e:/usr/local/bin/../lib/gcc-lib/i686-mingw32/4.1.2/../../../../i686-mingw32/include

in 'libraries: ='

 Of course when reverting back the old "standard", 
'$prefix/lib/gcc-lib', instead of the
new splitted '$prefix/lib/gcc' and '$prefix/libexec/gcc', that could 
have caused this bug,
but still with gcc-3.4 it didn't :

 For the gcc-4.1.2 prerelease this build was first for the MinGW host so 
maybe I patched
one of those "relative paths" away and these missings came from that...  
Maybe I should
first try the original "splitted/relative paths" settings before  
blaming the GCC developers...
