"We had problems compiling root with CC6.2 when applying the -D_REENTRANT
 flag, see forwarded mail below from a collegue of mine, Harray Felder.
 It does the minimal change I found necessary to be able to use the _REENTRANT
  define in our compilation of root. (This define is used to cause the system includes
  to generate some function calls instead of macros so that libraries
  can potentially be used in a multithreaded executable, although in a single-threaded
  manner. We are now setting this flag everywhere so that we can incorporate some
  libraries into java programs, which are inherently multithreaded.)"
