Hmpf, dunno what happened, so once again.

Yes, but i never used that "brown" tool. For one, i don't like its confusing
naming convention (depending on gcc version, it is "brown", "extrabrown",
"superbrown" etc). But more importantly, it needs an extra tool to be run
after linking, which requires Makefiles to be changed for all projects that
use it. That rules out most unix packages, where the Makefiles are generated
by autoconf, Cmake or similar. Also the whole toolchain requires a script to
be run on the mintlib (atari c-library) headers, which fails almost everytime
something in mintlib changes. And they did not even manage to provide a gem
library, or even a math library.
An alternative could be to use my mintelf toolchain, which is also available
on my site. This is based on the same sources as the normal toolchain, but can
be used as dropin replacement (just using a different target, or
BINUTILSPREFIX in our case). It will generate working executables in the same
way, but uses elf object format for compiling and linking, thus making all the
features of that format available. For fpc that would mean however you have to
tell it somehow that it can use elf features like sections, even when using
gas. I will give it a try at the weekend, i think fpc can be tricked by using
-Avasm, but then replacing the symlinks to the assembler.
If all else fails, i'm of course also ok with using vasm/vlink. There is only
the problem of the too long filename of the assembler executable. That should
be fixed i think, because it is also needed when running the *.ttp on TOS. And
of course i have to find out what causes vlink to put that strange program
flags in the header.
In any case, i agree that a hello world exe of 400k is not the best solution.
