Re: [Tinycc-devel] Sugggestion: Add lib type *.c for tcc_add_library() on windows ('-l' option parse)

[lifenjoiner]

Hi grischka,

What about document in 'tcc-win32.txt' by adding a libraries section as bellow.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Import Definition Files:
    ------------------------
    To link with Windows system DLLs, TCC uses import definition
    files (.def) instead of libraries.

    The included 'tiny_impdef' program may be used to make additional 
    .def files for any DLL. For example:

        tiny_impdef.exe opengl32.dll

    Put opengl32.def into the tcc/lib directory.  Specify -lopengl32 at
    the TCC commandline to link a program that uses opengl32.dll.


    Libraries:
    ----------
    TCC supports ELF object files and COFF resource files.
    MinGW gcc produces COFF object files, which tcc doesn't understand.
    And library (.a) files need compiled and made in this format.

    *
    c file also can be library by runtime compiling for linking.
    "-l" option searching priority is:
        name.def > libname.def > name.dll > libname.dll > name.c
    In the same dir, if a same name def file found and dll file not found,
    c file will be searched and added if found.


    Header Files:
