The format of the .map files seems to have changed with the linker upgrades.
Looking at .map files generated by the Z80 linker I see two problems.
1) Lots of 0x0c characters often at section beginnings.These show up as ^L or some other artifact when viewing the file.
2) Symbol lists are no longer continuous, but torn apart by inserted page headers. Having these page headers doesn't make much sense to me. They are annoying when viewing the file on the screen or processing them with a script. They are annoying when printing the file, unless one has exactly the right printer setting fro them.
I observed this problem using 2.9.7 #5642.
