 **   When manipulating the environment there is no way to un-set

 **   you interpret the return of a pointer to null-string to

 **   A call to PR_SetEnv() where the parameter is of the form
 **   "name" will return PR_FAILURE; the environment remains
 **   unchanged. A call to PR_SetEnv() where the parameter is
 **   of the form "name=" may un-set the envrionment variable on
 **   some platforms; on others it may set the value of the
 **   environment variable to the null-string.

 **   For example, to test for NULL return or return of the
 **   null-string from PR_GetEnv(), use the following code
