Hi Iain,
yes a configure option is a possible way around a conflict.
I was thinking more along making it a run-time option.
This is an option which will only be used by a developer,
who should know what the source code contains and what
the tool chain supports (and who can try out an underscore
if nothing else works).
So, something along the lines of -fdebug-aux-vars=: would be
equivalent to -fdebug-aux-vars, -fdebug-aux-vars=_ should work
on any system, with the (small) risk of colliding with user code.
How does that sound?
Best regards
Thomas
