[PD] creb compilation error

[plessas at sbox.tugraz.at]

dear pd-ers,
i get the following errors conpiling the creb library esp processing the
resofilt.c file
this is the output of my gcc, i'm doing this on osx, but it's a c-related
problem.

plus another question, has anyone had success running pdp on OSX, whenever i
want to open a window with pdp_glx my X11 (Apple's release) pd crashes. what
could be wrong? do i have to start pd from an osx terminal or from X11?

thanks to all!
