R-beta: Characters in .C

[Ian Wilson]

I am having some difficulties using dynamically loaded
C functions on a Sparc 10 with R compiled
using cc  (both R-0.49 and R-0.50).  I get sporadic errors with the 
error message:
Error: character variables must be duplicated in .C/.Fortran,
with C functions which pass character variables.

my C functions look like:  anyfunc(char **filename, other variables )

This error message appears about 25% of the time.

What is the problem ?
