I guess there's a new problem now [1]

It seems tcc -ar doesn't support the `x` command to extract an archive?

Building libressl borkes on this and I'm not sure hwo to get around it (yet).

Kind regards

I dunno what you guys did here[1] but you've solved all my compilation problems related to syslog.h :D Thank you!

I can now close all issues related to this in https://github.com/prologic/ulinux :)


Kind regards

Very cool!

That is it!  Great!  I tried to fool around to get the va thing
defined as a real type somewhere in the code base for an entire
afternoon, but simply enforcing the load of some special tcc
internal file is much easier.

  I was hoping for some kind of #include_next indeed, without ever
  being motivated enough to look in the codebase i have no plan
  of.  Like i said back in 2017 or so after grischka reverted that
  tccinclude commit of mine, i never understood why compilers
  install a tremendous load of internal headers which shadow or
  provide standard headers, like stdarg.h, but if you sprinkle
  #error's you note they never get even loaded.  Either you need
  it for proper functioning or not, i do not understand.  But
  granted the patch was much worse than what you are doing now!

Works much better now, great!  Thank you.  I hope he gets it done,
ulinux could be a really easy VM server thing for me.
(Unfortunately he removed a shell confirmation prompt() function
that was really neat; at least that function was in a pasteboard
thing i have seen.)
