[patch]: Add MS __ImageBase symbol to 32-bit pe.em

[Kai Tietz]

Hi Pedro,

> But, two underscores on __ImageBase on the C/C++ side links correctly.

AFAIC read, you are right. There must be two underscores in the header and 
therefore three in ld. I took a look at the MS headers (as Jerker did) and 
MS defines it with two underscores 8|
I will add the same issue to pep.em, too. Because I defined it there 
false, too.

I can just tell, that for the x86_64 version underscores are generated for 
symbols. And this target has the same base (for this configuration) as the 
32-bit version. So IMHO there are underscores.

ChangleLog for /ld/emultempl:

2007-11-02  Kai Tietz  <kai.tietz@onevision.com>

        * emultempl/pe.em: (init): Add __ImageBase symbol.
        (MSIMAGEBASEOFF): New.
        (set_pe_name): Keep __image_base and __ImageBase value synch.
        (_set_symbols): Likewise.
        * emultempl/pep.em: Likewise.

Is this OK for apply ?

Cheers,
 i.A. Kai Tietz
