Thanks for the suggestion. I've quickly tried it. I found that a couple of
subprojects which provide shared libraries for the other projects then got
rebuilt into two versions, one for each toolset. I presume then so stop
this that I would need to add a usage-requirements (? sorry, manual not
handy) specifying the toolset to these. And there will have to be a test
on the target OS to determine which toolset (vacpp or gcc) to use.
Obviously, I'd prefer not to have to scatter OS<->toolset mapping info
around the subprojects. Which brings me back to wanting to keep the
default toolset, but change the name of the command (as c4gl will call the
default platform toolset itself), but I'm not at all sure this is
possible.
