Hello all,

I am the coder behind the far pointer support for IA-16 GCC. Thank you very much for your comments!

Regarding .exe support, my fork of gcc-ia16 does have it, but it can only create "small" memory model .exe files, i.e. with 64 KiB code + 64 KiB separate data in total. Passing -mcmodel=small to my GCC front-end should enable the .exe support (the default is -mcmodel=tiny).

As for the actual implementation of .exe output: it is not in the binutils component, but actually in the newlib part (!). I use a linker script to fabricate the .exe header and lay out the code and data correctly.
