Nobody knows?

I did some trial and error by merging some debugging related revsions
from http://www.stack.nl/~marcov/fpctomerge.txt
but I failed.
Also I noticed that some revisions are not on that list, for example
r14068, probably because it is blocked, but its changes in dbgbase are
used in later revisions. So I got stuck.

What would be the best way to proceed to identify the fixes in fpc
2.5.1 for DWARF info to be included in fpc 2.4.3 or a patched fpc
2.4.2?
