Is there any reason why `pathconf' always returns static info?  For 
example, the NAME_MAX and PATH_MAX parameters can change at run time, if 
you are on an LFN platform, but `pathconf' always reports the low 
DOS-based values.  Does POSIX specify such static behavior?

If not, then I can post the necessary patches (they are trivial).  Then 
we could use `pathconf' as a vehicle to make DJGPP ports of Unix programs 
aware of the maximum length of the filename on any given filesystem.  
Currently, the ports use `_USE_LFN' macro for that purpose, but that is 
inherently DJGPP-specific and requires #ifdef __DJGPP__, whereas 
`pathconf' is POSIX.
