[R] Fortran subroutines dblepr, realpr, intpr

Further to my earlier request for help (see below): I should have
said what operating system and compiler I am using.
I am working with the (mingw) g77 compiler under Windows 2000, and
following the approach outlined in Venables & Ripley's "S
Programming", p243. That is, with my Fortran code in testit.f, I say
g77 -O2 -c testit.f
dllwrap -o testit.dll --export-all-symbols testit.o
which works fine when I don't have any print statements in testit.f,
but if for example I call INTPR in testit.f the dllwrap step fails
with the complaint
undefined reference to `intpr_'
dllwrap: gcc exited with status 1
Any hints will be much appreciated. As I said earlier, I am just
beginning with this.
