Changes since version 2.5:
* When an ELF section name is representable as a C identifier (this is not true
of most ELF section names), the linker will automatically define symbols
__start_SECNAME and __stop_SECNAME, where SECNAME is the section name, at the
beginning and the end of the section. This is used by glibc.
* When an ELF section named .gnu.warning is encountered in an input file, the
contents of the section are displayed as an error message, and the section is
not copied into the output file. This is used by glibc.
* New options -split-by-reloc and -split-by-file.
* The linker now supports linking PIC compiled code on SPARC SunOS. It still
can not create SunOS shared libraries.
* The COFF linker now combines debugging information for structs, unions, and
enums, so that even if the same type is defined in multiple input files it will
only be defined once in the output file. The --traditional-format switch will
prevent this optimization.
