It's orthogonal.  You muck with multiple threads?  So use TLS.  You 
happen to call another qsort() recursively from the callback?  So just 
in the callback copy the global variable to stack before touching it, 
and restore when the inner qsort() finishes.

You saved exactly *two* (declaration and initialization of one static 
var) LOCs out of 14, using a feature requiring substantial (but hidden) 
support at compile time (especially difficult to implement in a 1-pass 
compiler the TCC is), and at runtime (hidden 16-byte trampoline on the 
stack).  Is that 'simpler'?

Oh, great.  Like fine scoping?  So move these "unrelated" functions to 
another file and you're done.

Unrelated, see above.
