No, it seems to be the compiler that ignore lower and upper case path  
names. This is the error message
..

/System/Library/Frameworks/Foundation.framework/Headers/NSArchiver.h:

Note that the error is an effect of illegal Objective-C statements in  
plain C.

Yes, the lowercase check. But I can't find reasons to include this on  
Mac OS X (or any old NexStep system).

This is because I searched for function calls NS...(...), i.e the  
common prefix for appkit.h functions, but there isn't even a match.  
Typcial cases where I expected to find such calls would be HTUser.c,  
HTInet.c, etc., i.e. for quering user name, home path, etc. But BSD  
routines are used instead.

If there are no need for this header in the library, is there any need  
for this check then?

Removing this check would reduce configuring time.
