 you are missing the point.. only gcc-2.95.x uses toc entries so
 inefficiently that either -bbigtoc or -mminimal-toc is required.
 neither xlc, nor gcc-3.x required any workaround at all.

 They are basically the same, Unfortunately the AIX/XCOFF gnu linker
 will not support -bbigtoc (or any equivelent), so your breaking that
 anyway.
