Re: CRAY-style vector functions in AltiVec?

Perhaps the problem was more specific: I saw the trick of naming a subroutine in fortran with a given name, and naming the same same subroutine in C with the same name with an underscore suffix. The link failure occurred when the fortran subroutine had an underscore within the name. Hence, in Ian Ollman's example from the Apple DC pages, the following names did not work:

fortran:
call start_clock()
C:
start_clock_( void )

but these names DID work:

fortran:
call startclock
C:
startclock_( void )

Cheers,
Marc

One thing about g77 is that its default behavior is to add 2 underscores at the end of a subroutine name when the name contains an underscore (instead of the normal 1 trailing underscore). It can be forced to do only one with -fno-second-underscore. This may the source of your linking problems.
