RCOMP error message line numbers

I spent a few hours trying to track down a syntax error in an RSS file
(should have resorted to binary search earlier :-().

The reason it was so hard to find, was that RCOMP was reporting the line
number wrong. It seems that all RCOMP versions upto the 8.0a  SDK reset
the line number counter to 0 when they see then
# 283 "ContextMediaUi.rss"
line produced by the preprocessor, instead of setting it to the
specified number (283 in this case).

I've now copied the 8.1a RCOMP to the earlier SDKs and am using that.
Fingers crossed, that the resource files it generates are compatible.
