I can see the attraction for an IDE user, but for a regular command-line user 
this pushes the gcc error messages way over to the right and in most cases on 
to another line (note that the word-wrapping below does not match my terminal 
output which is more ragged):

Original:
../../../src/std/softIoc/softMain.cpp:9: error: ‘syntax’ does not name a type

Using $(abspath $<):
/home/phoebus3/ANJ/epics/base/mirror-3.15/src/std/softIoc/softMain.cpp:9: 
error: ‘syntax’ does not name a type

I would consider adding a build configuration parameter in the 3.15 version so 
this could be enabled by those who want it, but I wouldn't want it to be the 
default, which I think you suggested would be acceptable.

I have a simple and working solution which I will discuss with Janet tomorrow. 
The tricky question is how far to go with using it — do the dependencies need 
to be absolute?  What about calls to flex and antelope?  Resource compiler?
