Hi Francesco,
I've also been working a bit on getting tcc on the Mac to work. So
far, it compiles and runs, but the major hurdle now is that it
produces ELF binaries, and also expects to be able to link with ELF
binaries/libraries, as far as I can tell even when being used as a
JIT. This doesn't work as OS X uses Mach-O.

i'm a mac user and 'i'm really looking forward to use the library
cinpy on my mac, in order to mix python and c code. To do so, i have
to install the tiny c compiler. I downloaded the sources and made
the following steps:
My diffs are below, the resolve the register name issues you
encountered and an alignment problem that you will probably run into
right after that.
