DJGPP script update patch
- To: binutils@sourceware.cygnus.com
- Subject: DJGPP script update patch

This is one more update (and hopefully the last for a while) to DJGPP's linker script. It
deletes the ___EH* symbols that proved unneccessary (but LONG(0) still is for gcc 2.8.1)
and corrects some semicolon typos. It also adds support for the init_priority attribute
in g++ 2.95. Note I used .?tors. not say .?tor. because the name is hardcoded in
gcc/cp/decl2.c.
