Yes, absolutely.

I think there's a misunderstanding of what <subproject> is. It's a way 
to build another set of targets that don't depend on targets in the 
"parent" makefile (and a makefile of its own is created for 
subproject). If you have an executable target that depends on a 
library, then you should do something like this instead:

<lib id="guidelib">
....
</lib>

<exe id="demo">
   <library>guidelib</library>
</exe>

The <library> tag makes guidelib a dependency of demo and ensures 
correct linker settings.

Because you can't make a .dsw depency of another .dsw file and at the 
time demo.dsw is generated, nothing is known about the content of 
guidelib bakefile so it can't infer what dsp files there will be (so 
that it could make all of them dependencies).

That's because there's no way (that I know) to save & restore current 
directory in Borland's make. Maybe it's possible to workaround it 
somehow, but I don't (yet) know how. The underlying cause is that 
<subproject> is meant to be used with subdirectories, not 
subdirectories of parent directories.
