Hi Tkchia,

Thanks for that information! I vote HXRT. I found those hex bytes in DPMILD32.EXE and here is a link to the code corresponding to your disassembly:

https://github.com/Baron-von-Riedesel/HX/blob/master/Src/DPMILDR/DPMILDR.ASM#L2864

Interesting that this behaves differently in FreeDOS than in SvarDOS.

Note that i can compile and run hello world with the bootstrapped TCC.EXE. It's not until i try to build TCC with the bootstrapped TCC.EXE that i run into problems on FreeDOS.

p.s. I could probably work around this first issue by using TCC's @file syntax for the overlong command line options.
