 The Makefile for Python SWIG uses LD for linking rather than GCC. On some
 Linux systems, this causes Python to throw the error:

 $ python -c "import _python_grass6"
 Traceback (most recent call last):
   File "<string>", line 1, in <module>
 ImportError: ./_python_grass6.so: undefined symbol: __stack_chk_fail_local

 when the library python_grass6 is imported due to a stack smash guard.

 I have confirmed that replacing LD with CC fixes this problem. On some
 distributions of Linux, this can be fixed by adding "-fno-stack-protector"
 to CFLAGS.

 R.
