Or libtool, if you use it to link your exe?  PTC...since $new-libtool is 
pretty high on my to-do list.

It'd be better if there was an option to ld/gcc, of course -- but the 
details would be rather complicated.  You wouldn't want to invoke a 
separate executable like windres b/c then your build recipe/makefile 
would have to change.  Best if $LD_FLAGS could be used... maybe 
something hideously ugly like -w32-manifest-compat <file> [1] where 
<file> is not a full XML manifest, but rather contains a list of GUIDs 
[2], and ld/gcc autogenerates the manifest with just that stuff.

That way, if you manually create a manifest (for other purposes), you 
could just /not/ use the new flag.

I know, SHTDI...

[1] or comma-separated list of GUIDs? That'd get long and ugly, very fast.

[2] not OS names, b/c then (a) ld/gcc would have to "know" the 
corresponding GUID, and (b) the GUID<->OS database would be out of date 
and require a binutils/gcc patch every time Redmond released a new 
service pack.
