GCC is 2.7.0, linked with libc5. Taken from mulinux.

Tcc is 0.9.24. I had to slightly modify its source code and makefile to 
make it compilable under Basic linux and libc5. Later I self-compiled it.

Also, nasm and upx from mulinux work under basiclinux, with libc5. I 
think that asmutils can be combined to single executable like
busybox and we will have busybox functionality in even less space. 
Currently, every tool from asmutils is tiny, but disk cluster size 
nullifies this advantage.

Hmm, I did not try, but as floppy based Linuxes are already compressed, 
UPX will not help, because compressing compressed file usually gives 
worse results
than compressing uncompressed. It will take less space in RAM disk, 
however. But there are some other ways:

- Format floppy to 1.7 megabytes
- Implement busybox from asmutils to make it smaller
- Recompile Xwindows with tcc hoping that his linker will be more smart 
(tcc compiled with gcc is 330K, tcc compiled with tcc is 170K) (but tcc 
generates less optimised code, so it will be slower). I also prepared 
one scientific paper about generating tiny executables with gcc compiler.
- Remove some unused GUI tools.
- Try to compress second floppy using bzip2 instead gzip and change boot 
script.
- Prepare module on third floppy and install it after booting using pkg.
