The stub size in GO32 executables has historically been fixed at 2048 bytes, due to hardcoded limitations in bfd. Recent patches to djgpp by Stas Sergeev (CC'd) have pushed the stub right up to this limit, so if any further expansion is desired, this must first be patched in bfd. This series includes three patches: The first changes the meaning of the bfd->origin field slightly, so that target code can use this to specify an offset into the file where the actual bfd is located. The second patch then uses this to enable support for variable-sized stubs in the coff-go32-exe format. The final patch is only a cleanup, it normalizes function and variable names in coff-stgo32.c so that they all begin with the same prefix. bfd * bfdio.c (bfd_bread, bfd_tell, bfd_seek, bfd_mmap): Always add bfd->origin to file offset. * bfdwin.c (bfd_get_file_window): Likewise. * bfd.c: Clarify the use of the bfd->origin field. * bfd-in2.h: Regenerate. * coff-i386.c: Don't include go32exe.h.
