I forward a mail posted on tex2pdf-devel.
Anyone aware of this and recommanding to force the switch ?
(may be useful for internal LyX graphics conversions).

[snip] thread about the fact that backconversion of bitmapped
eps to pdf via epstopdf may fail if the switch is not set;
avoided is the original bitmap is present, but may happen
with eps of unknown origin or (to be checked) exported from xfig

So what's going on ?
I ran through the GS doc, and found nothing about
the -dCompatibilityLevel switch.
I think a bit annoying to force an undocumented GS option,
anyone knowing something about this ?
On the other side, further checks show that the error
may highly depend unpon the local screen fonts installed
(same file, same acroread binary, different behaviour
on different computers), so the option seems compulsory
when wide diffusion is planned, even with a correct
behaviour on your screen.
The printed stuff must be OK, but if we provide hyperlinked
PDF, it's to read it on screen...
