Re: [Tinycc-devel] tcc compilation on MSYS2

[Chris Marshall]

Thanks for the help.

I've got tcc building but the bcheck.c compile is failing
when the stdlib.h is pulled in.  My next step is to try
the same with the latest tcc git.  I'm not sure what the
best way to proceed woud be.  The top level gcc build
can correctly (for cygwin) process the various system
include files.  It is only when tcc tries to process those
same files that the problems start.  Maybe there is a
wayto use the gcc step to generate a tcc version of the
include files.

Also, with this patch, I believe that it will prevent enabling bcheck when creating a cross compiler tcc from cygwin for a platform which does support bcheck, since I _think_ this will set tcc to define __CYGWIN__ when compiling [cross] tcc itself.

I might be wrong here though, I didn't check much of the surrounding code.
