[PD] compiling errors for expr~ on win

[Mark Khemma]

Hello,
I'm attempting to build the expr~ external on my win machine and i'm
getting errors from nmake:

'FUNC_EVAL'

All the errors are pointing at this line in vexp_fun.c
	FUNC_EVAL(left, right, min, /**/, /**/, optr);

Anybody know how i can fix this, or where i have gone wrong?

Thanks,
