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

[lifenjoiner]

Hi there,

I work on win platform.

As tcc can't use gcc's library (*.a) file, tcc can use *.def file (ONLY) for 
dynamic link avoid making the library files.

For many libraries small or simple, I think tcc also should can use *.c file 
(ONLY) as library.

For complicated case, library contains *.def and *.c files (BOTH), I think tcc 
can try "*.def + *.c" instead of *.a as library.

So tcc can use all files as scripts. I used shell scripts for this purpose 
before. :p

My changes on "libtcc.c" are bellow:

-----------------------------
/* the library name is the same as the argument of the '-l' option */
LIBTCCAPI int tcc_add_library(TCCState *s, const char *libraryname)
{
#ifdef TCC_TARGET_PE
    const char *libs[] = { "%s/%s.def", "%s/lib%s.def", "%s/%s.dll", 
"%s/lib%s.dll", "%s/lib%s.a", "%s/%s.c", NULL };
    const char **pp = s->static_link ? libs + 4 : libs;
#else
    const char *libs[] = { "%s/lib%s.so", "%s/lib%s.a", NULL };
    const char **pp = s->static_link ? libs + 1 : libs;
#endif
    while (*pp) {
        if (0 == tcc_add_library_internal(s, *pp,
            libraryname, 0, s->library_paths, s->nb_library_paths)) {
#ifdef TCC_TARGET_PE
            if (pp < libs + 2)
                tcc_add_library_internal(s, *(libs + 5), libraryname, 0, 
                    s->library_paths, s->nb_library_paths);
#endif
            return 0;
        }
        ++pp;
    }
    return -1;
}
-----------------------------

My tests succeed. Can it be submitted?
