Howdy all,

I'm having some wierdness with my attempts to build a hello world program.

Attached is the makefile and the .c file. You'll obviously have to adjust
it to suit your environment, but is there something obvious I'm doing wrong?
The test programs (bin_sem0, for instance) seem to work fine.

See ya,

Nick
