Hello,

The below two patches fix some problems with i386-elf executables running on boards with either cygmon or redboot. Bernd's patch prevents eh_frame from walking all over redboot's active memory. Mark's patch aligns __CTOR_LIST__, preventing a SIGILL at start time. Both patches are tested against gcc 3.2.2+binutils 2.13. The application of the two patches solves a couple hundred gdb.c++ test cases for me.

* i386/cygmon.ld: Add 4 byte alignment to __CTOR_LIST__

2001-12-17 Bernd Schmidt <bernds@redhat.com>

* i386/cygmon.ld: Add entry for .rodata.
