Concentrate compiler dependencies to compiler.h; make sure compiler.h
is included first in every .c file (since some prototypes may depend
on the presence of feature request macros.)
Actually use the conditional inclusion of various functions (totally
broken in previous releases.)
- Panos Minos's LDRDF fix (correct export of relocation records);
- Panos Minos's symtab.c verbose dump fix;
- Librarian (rdflib) now puts a signature block when creating a library
(instead of creating an empty file). In theory it doesn't break binary
compatibility, but due to a bug in the original 'rdlib.c' you can't
use old LDRDF with new libraries. Fix this bug as well.
- Other minor changes in LDRDF.
