Another unsupported compiler

[ghost]

Different from the previous: https://github.com/gobo-eiffel/gobo/issues/58

It's Pelles C. See: http://www.smorgasbordet.com/pellesc/

There used to be a request to support Pelles C, but closed: https://github.com/gobo-eiffel/gobo/issues/54

Pelles C is very similar to MSVC. But it's much smaller. So more suitable for people doesn't have plenty of disk space to install MSVC. The generated binaries are still fast, comparable to MSVC.

It seems these bootstrap source files are for MSVC in mind. Even though Pelles C is so similar to MSVC, still not work out of the box.

@ebezault Please support Pelles C.

Pelles C has full document about the command line compiler. Install it and check help0009.chm on C:\Program Files\PellesC\Bin\Help

This is pocc.cfg:

You could see. Almost no different to msc.cfg

This is the hack I put on bootstrap.bat:

...
if .%CC%. == .pocc. goto pocc
...
:pocc
    set CC=pocc
    set LD=polink
    set CFLAGS=/MD /MT /Ze /O2 /std:C99 /Wd2215 /Wd2251
    rem /Wd2030 /Wd2114 /Wd2115 /Wd2154 /Wd2205 /Wd2215 /Wd2238 /Wd2251
    set LFLAGS=/subsystem:console
    set LFLAG_OUT=/out:
    set LLIBS=
    echo pocc > %GOBO%\tool\gec\config\c\default.cfg
    goto pocc_compilation
...
:pocc_compilation
    if not .%VERBOSE%. == .-s. echo Compiling gec (bootstrap 0)...

Still gec9.c, it's the most annoying C source file I have ever tried to compile.
