Actually the -mcall-aix support is to be compatible with the calling sequence GCC used before I added the eABI support. I think Kenner was the original author. There are major Cygnus customers that still use it, so I would prefer it not be removed, sigh.... The -mcall-aixdesc switch, which is not documented, was my attempt to merge the two major ABIs into one compiler (this was before I added the now defunct NT support). When I moved to a faster computer (from a 90 Mhz Pentium to a dual 200 Mhz Pentium Pro) and my builds became much faster, I lost interest in trying to use one compiler to support all of the ABI's. -- Michael Meissner, Cygnus Solutions PMB 198, 174 Littleton Road #3, Westford, Massachusetts 01886 email: meissner@cygnus.com phone: 978-486-9304 fax: 978-692-4482 ------ Want more information?
