[fpc-devel] .long values in DWARF Symbols

[Michael Ring]

Looking very good, I could load and debug a small app with a rtl built 
with -gw2

Thank you very much for the fix!

I have now reduced the filesize of the embedded-units so that they 
should be small enough to be included in fpc:

-rw-r--r--  1 ring  staff  33568 22 Mai 17:55 pic32mx1x0fxxxb.pp
-rw-r--r--  1 ring  staff  33614 22 Mai 17:55 pic32mx1x0fxxxc.pp
-rw-r--r--  1 ring  staff  33719 22 Mai 17:55 pic32mx1x0fxxxd.pp
-rw-r--r--  1 ring  staff  40189 22 Mai 17:55 pic32mx1x0fxxxh.pp
-rw-r--r--  1 ring  staff  40325 22 Mai 17:55 pic32mx1x0fxxxl.pp
-rw-r--r--  1 ring  staff  39039 22 Mai 17:55 pic32mx2x0fxxxb.pp
-rw-r--r--  1 ring  staff  39085 22 Mai 17:55 pic32mx2x0fxxxc.pp
-rw-r--r--  1 ring  staff  39085 22 Mai 17:55 pic32mx2x0fxxxd.pp
-rw-r--r--  1 ring  staff  45550 22 Mai 17:55 pic32mx2x0fxxxh.pp
-rw-r--r--  1 ring  staff  45686 22 Mai 17:55 pic32mx2x0fxxxl.pp

So I will have something to play with when traveling to Maker Faire in 
Hannover this weekend ;-)
