[Tinycc-devel] Allow tcc arguments to be read from @listfiles

[Vladimir Vissoultchev]

Hi,

The first patch allows sourcefile names to be passed in external listfiles
in the way most compressing utilities (7-zip) work. Listfiles are passed on
the command-line as '@' prefixed filenames and can contain tcc options
besides source files, each on a separate line, starting whitespace is
ignored.

The second patch is just an expansion of winapi header files to be able to
compile nginx under windows w/ tcc. Here are results from -bench on 5 times
multiplied nginx source files:

C> tcc.exe -bench -c -D__GNUC__=4 -I src/core -I src/event -I
src/event/modules -I src/os/win32 -I objs -I src/http -I src/http/modules

Here is a report by function from VS profiler on this bench run:

It seems the process is I/O bound with builtin `__open` being first but the
low hanging fruit is `next_nomacro1` function
