What steps will reproduce the problem?
1. configure compile on aix, solaris or similar boxes
2. compile on windows using MSVC
3.

What is the expected output? What do you see instead?

The compiler fails with syntax errors, as it doesn't handle // as a
comment. On windows it fails with a missing unistd.h error/

 Attached a patch fixing the problems.

Bootstrap script will not work from a tclkit without tcl installed

Creating of so files on Linux coredumps

The code contains gcc-isms as "long long" and "inline" so it can't be 
built with VC

make install doesn't install the tcc.tcl file

What steps will reproduce the problem?
1. Build tcltcc
2. Change file tcltcc.c
3. Do a make

What is the expected output? What do you see instead?

Library will be rebuild. Instead make will indicate there is nothing to be 
done. This has to do with tcc including the c files instead of compiling 
them to .o files and linking them together. Either the TEA config should 
be adapted to add the .c files as dependencies, or the include of the c 
files should be removed. Currently a make clean ; make is required

Currently tcltcc will select the code generation backend at compile time. 
It would be very useful to be able to select the backend a runtime so it 
will for instance be possible to generate win32 dlls on linux

What steps will reproduce the problem?
1. configure
2. make

What version of the product are you using? On what operating system?
Linux 2.6, gcc 3.4.6, tcltcc 0.2, tcl8.4

Please provide any additional information below.
I have compiled the standalone tcc under linux with no problems.

Having the parser/frontend as a tcl command opens up the possibility of
using  it as the input for other code processing tools. Pretty-printing
would be a low thing among that, more important would be tools doing static
code analysis, static call graph generation, etc. Instead of doing their
own parsing they can process structured data in the form of an AST. And be
written in Tcl.

The following error is shown on link:

Current workaround:

relink with:
gcc -shared -o tcc02.dll tcc.o  -L/c/Tcl/lib -ltclstub85 -Wl,--exclude-
libs,tclstub85

Only one set of commands, or rather, methods of an object, and object can
be configured for the asm to generate, and where to.

The Tcl_Obj containing the string stored in s->tcc_lib_path is leaking on 
command deletion. Should store the Tcl_Obj * instead so the refcount can 
be decreased in  TccCCommandDeleteProc.
