Building GCC 3.3 / MingW

[Lars Andersen]

I have successfully build the cross compiler, host=linux, target=mingw,
with the following sources :

binutils-2.13.90-20021006-2-src.tar.gz
gcc-20030210.tar.gz
mingw-runtime-2.4.tar.gz
w32api-2.2.tar.gz

follwing Ranjit's directions as in 
http://ranjitmathew.tripod.com/phartz/gcj/bldgcj.html#xgcc


Mohan Embar posted the following problems, here is how I solved them :

applied this patch :

The XGCC_BUILD_DIR where the cross gcc is build MUST be named
"g++_build". Guess there is a hardcoded path somewhere! With this in
place testsuite compiles.

applied the patch mentioned


Next I encountered problems with
./libjava/java/net/natPlainDatagramSocketImpl.cc
ECONNREFUSED is undefined (appears in 4 places)

>>>>>>>
if (errno == ECONNREFUSED)
   throw new PortUnreachableException (JvNewStringUTF (strerr));
<<<<<<<

I just commented those lines out. This is of course an ugly hack, but on
the short term only means that the wrong Exception gets thrown.
