It would be exciting to add 16-bit x86 assembly support to tinycc,
if this could be done without a remarkable size penalty.

Then tcc would correspond to the whole OS toolchain for Linux-2.4 on ia32
and x86_64, without the need for the binutils or something else for the
16-bit boot code (I used f.i. the 16-bit assembler from the Amsterdam
Compiler Kit).

Michael's answer went to the list.
For completeness, my original question was:

Hello Michael,

You have made an impressive job.

I feel especially interested because I made a similar effort
in a smaller scale for VSOBFS [1]
but it did not look like musl and linux 2.4.26 would work together,
nor does musl claim compatibility with kernels before 2.6.

I solved this by using a different libc,
how did you approach this issue?

Kind regards,
