[Rd] problem with va_list type (alpha) (PR#421)

[albrecht.gebhardt@uni-klu.ac.at]

Full_Name: Albrecht Gebhardt
Version: 0.99.0
OS: alpha, osf4.0
Submission from: (NULL) (143.205.180.40)


Both DEC cc and gcc complain (osf4.0, alpha) about applying
an unary operator (!) to a non scalar type (va_list arg) in 
printutils.c

I'm not sure if I understood what was intended by "!arg" (see below),
but with this patch I at least was able to compile. (and R runs now,
but I guess only because I didn't came across this code section)
