Yaargh. 
 
Not sure what I need here. 
 
Make sure you have a clean checkout and a clean build directory.  :-/  And 
that you're using GNU make.  And a working shell (preferably bash; or ksh). 
 
It seriously looks like a bug in mkdir.  I can't reproduce the "mkdir: No such 
file or directory" or figure out where it's coming from; that should *never*  
happen with mkdir -p. 
Perhaps Solaris 'mkdir -p' doesn't support -- , isn't thread-safe, can't 
handle directories which already exist, or doesn't actually work? 
 
Try running this and see if it works: 
mkdir -p -- sparc-sun-solaris2.8/libstdc++-v3 
If it fails, we have our bug. 
Try it again to make sure it works in all these cases: 
(a) neither directory exists 
(b) sparc-sun-solaris2.8 exists and sparc-sun-solaris2.8/libstdc++-v3 doesn't 
(b) both directories exist 
 
If that works, try running these all at the same time (how best to do this I 
don't know), under the above situations: 
mkdir -p -- sparc-sun-solaris2.8/libstdc++-v3 
mkdir -p -- sparc-sun-solaris2.8/libiberty 
mkdir -p -- sparc-sun-solaris2.8/libf2c 
If one of these fails, this indicates that mkdir -p isn't thread-safe. 
If so, it's not GCC's problem.  :-/
