 Yes, standardized, but I read the standard so that PATH_MAX is not 
 required to be defined by limits.h:
 
 "The values in the following list may be constants within an 
 implementation or may vary from one pathname to another. For example, 
 file systems or directories may have different characteristics.
 
 A definition of one of the values shall be omitted from the <limits.h> 
 header on specific implementations where the corresponding value is 
 equal to or greater than the stated minimum, but where the value can 
 vary depending on the file to which it is applied.  The actual value 
 supported for a specific pathname shall be provided by the pathconf() 
 function."
 
 Notably, not just may be omitted, but shall be omitted.
 
 Anyway, if Hurd does define PATH_MAX, we can use it, but if not, 
 changing the identifier doesn't solve anything no matter what the 
 standard says.
