I'd prefer to drop 3.3 and use 3.4 instead, for reasons that I've 
previously described.  The current state of the 3.4 compiler is actually 
close to, if not better w.r.t. less bugs than the 3.3 RISC OS compiler.

We could add iconv as a library that's automatically built and 
distributed with GCCSDK, simply by adding it to the riscos-libs 
directory.  That was the original intention of that directory.

Things I would like to see are:

a) A working Java compiler.  The framework is there now.  I haven't 
tried to test the system yet because garbage collection was the sticking 
point.  However it is possible to run without a garbage collector.

b) A working Ada compiler.  The support of pthreads in UnixLib probably 
solves the main sticking point, which was Tasking.

c) Anybody care about Objective-C ?  It's easy to port the compiler, but 
got knows about any of the run-time libraries.  It depends on whether 
you want GNOME for RISC OS, I suppose.

d) UnixLib headers fixed to conform to the ISO C99 and ISO C90 
namespaces.  I think this is becoming more critical for compilance with 
the Standard C++ Library.

e) Better RISC OS specific documentation and more information and 
tutorial on what the myriad of ARM-specific compiler options do with 
contrived examples and resultant ARM assembler output.  This becomes 
more sigificant when you start looking at unit-at-a-time mode in GCC 3.4 
and the tree optimisation stuff in GCC 3.5.

Can't think of anything else.
