Simulator question about argc/argv

Some new tests have been added to the GCC testsuite (cilk tests) that
check the value of argc and they expect it to be 1 if there are no
arguments to the test program (and there are none) but I am getting 0
when I run the tests under the gnu simulator.  Does anyone know why
this is?  I don't know if this is specific to my target (mips-mti-elf)
or a general simulator problem.  Perhaps it is related to my linker
script?  The mips-mti-elf target is built with newlib.  Could someone
else who uses the gnu simulator and newlib try this.  It works fine for
me under the qemu simulator.

% cat x.c
#include <stdio.h>
int main(int argc, char **argv)
  printf("%d\n", argc);
  return 0;

% mips-mti-elf-gcc x.c -Tmti32.ld -o x
% mips-mti-elf-run ./x
% mips-mti-elf-run ./x 99
