I have followed these steps:

this gives 7 packages core,g++,...objc


I note that the structure is a little different from that of the
official packages actually present in Cygwin:

   - no libphobos* build
   - part of D compiler is in gcc-core instead of gcc-gdc
   - some *.a file in i686-pc-cygwin instead in i686-pc-cygwin/3.4.4
   - some includes for D not installed
   ...

I confirm: it takes almost 12 hours on 1.3 GHz processor for the build
step (./gcc-3.4.4-1.sh build).

I Confirm. I have accepted the default hoping it works, too.

In any case I am mainly interessed to gcc, g++, g77.

From the mailing list it seems to be urgent some fix to GCC in Cygwin. 

In the Cygwin distribution there are packages like Octave that are
incompatible with gcc-3.4.4-1, yet.


Cheers, 
  
   Angelo.
