RE: [Tinycc-devel] I want to port make on Windows using tcc compiler

[Christian Jullien]

Ooops, Yes DIRENT is needed. I sent you an incomplete diff. Enclosed are the
right ones. This new build_w32.bat allows both tcc and cl to compile dirent.
You can replace c11 by c99 if you like. I generally use c11 which sometimes
checks about deprecated uses.

Tcc supports loadable libraries (.dll on Windows and .so on linux). If you
never heard about tcc before, I invite you to give a try and see the
phenomenal compiler speed. It makes you think you have an interpreter which
of course dramatically boost your development cycle. It even support
on-the-fly compilation with shee-band #!/usr/local/tcc. This way you can
make shell scripts in C. Compiling a working Linux kernel is a matter of sec
(see https://github.com/seyko2/tccboot)
Execution speed of this one pass compiler is fair: 30 to 50% slower than gcc
or cl. This is my main C compiler I use daily for C devel (no C++). When
code works, I polish the binaries with cl or gcc with all possible optims
for my OpenLisp Lisp compiler. This a must have on RPi for example.

For sure, I'll be glad to do so.

Thanks.  A few questions and comments below.

What is this part about?  Is it needed, and if so, why?

Why are you using -std=c11 here? this is unlike all the other
compilations, which use C99.

Does this build the import library?  And in general, does the tcc
build support loadable modules?

Last, but not least: a contribution this large will need you to sign
legal papers assigning the copyright to the FSF.  Would you like me to
send you the form to fill to start the legal paperwork?

Paul, any comments?  The changes look reasonable to me, FWIW.
