I wonder if this idea could be extended to enable $@_CFLAGS and similar.

The current version was:

...

So if a header following this pattern didn't otherwise include shareLib.h afterward,
the epicsShare* qualifiers would not be defined.

The fix is to include shareLib.h unconditionally.

I recall hitting instances where this was happening, but can't find them again at present.
I guess we'll find out when something breaks...
