* Support for i386-sysv. configure.in: check for i386-*-sysv* and i386-*-sco*. i386coff.sc-sh: rewrote to support SVR3 by default. ldctor.c (find_constructors): preserve stat_ptr. ldlang.c (wild_doit): initialize vma and size of new output section to corresponding input section. This is required for shared library support. (lang_size_sections): don't modify vma and size of sections which are never loaded (for shared libraries). ldwrite.c (copy_and_relocate): copy the contents of any section which has contents, not just sections which are loaded (for shared libraries).
