But only because we don't have #ident lines in all the header files.
Do that and 'mcs -c' is your friend.
IMHO we should build without removing any symbols, then strip for
installation. The assumption then is that the build tree has the
symbols in it - maybe the unstripped binaries should be available
for the release CDs?
I have had to rebuild programs because they get stripped during build.
That is bad news. Also removing local symbols can give apparrantly
incorrect stack back-traces, so isn't particularly useful.
It it also possible to do a reasonable amount of debugging with just
the standard symbol table - after all the most usable feature of gdb is
the 'bt' command on a core dump.
