Tim Prince,
Thanks for ur response. I am using 32 bit OS ( Suse Linux
/i386) but i need to compile for 64bit. coding is doen well
with standards. the main need is porting the compiler itself.
please help!
Thanks & Regards,
Syam Prasad N

cygwin doesn't support 64-bit Windows development. I certainly hope it
may do so at some time not too far distant.
If you write standard C code, rather than taking steps to make it a
non-portable "32-bit" code, you should be able to make it run both on
linux x86-64 (64-bit) and on i686-pc-cygwin (32-bit). If you are
talking about porting the compiler itself, which I understand is a cross
compiler, there may be no advantage in turning it into a 64-bit
application, since the x86-64 OS supports 32-bit mode perfectly well.
