* changes to support i386-sysv with shared libraries: * coffcode.h (sec_to_styp_flags): if TWO_DATA_SECS is defined, check for .data2; if _LIB is defined, check for it; map SEC_NEVER_LOAD to STYP_NOLOAD. (styp_to_sec_flags): map STYP_NOLOAD to SEC_NEVER_LOAD. (make_a_section_from_file): if TWO_DATA_SECS, accept .data2. (coff_write_object_contents): force vaddr of .lib to 0; set scnptr if section has contents, not just if it is loadable; if TWO_DATA_SECS, check for .data2 (coff_set_section_contents): set vma of .lib section to number of .lib sections. * coff-i386.c: define TWO_DATA_SECS; use a special CALC_ADDEND; don't define coff_write_armap to bsd_write_armap. * hosts/i386v.h: don't include <utime.h>, since it is not provided by SVR3.2.

check for .data2; if _LIB is defined, check for it; map

(styp_to_sec_flags): map STYP_NOLOAD to SEC_NEVER_LOAD.

(coff_write_object_contents): force vaddr of .lib to 0; set scnptr

(coff_set_section_contents): set vma of .lib section to number of

don't define coff_write_armap to bsd_write_armap.

by SVR3.2.
