I stand corrected. In order for this to work, the initializer must be  
known at compile time (it should be a constant, since it is filled in  
by the compiler and not at runtime). So instead of

     static const char *path = getfullpath(PATH_ETC);

this should be split in

     static const char *path = NULL;
     if (path == NULL) {
         path = getfullpath(PATH_ETC);
     }

This will assign 'NULL' to 'path' at compile time and at runtime, will  
try to read the path as long as it stays 'NULL'. This means that it  
will only be assigned a value the first time this is executed.

Best regards, Arjen
