/* Currently load_foreign_files works for the following machines:
|
|
|
|
AIX: should work for 3.2 and 4.1 at least, using ECOFF;
|
|
linux: should work both for a.out (untested by me) and ELF;
|
|
osf: should work, but isn't working yet.
|
|
sunos4: should work, using A.OUT format;
|
|
svr4, eg solaris: should work, using ELF format;
|
|
|
|
YAP should be able to load on most BSD Unixes, but you will need to
|
|
say that here.
|
|
|
|
YAP also supports COFF loading (pretty much the same technique as
|
|
used for A.OUT loading) but that is untested so far.
