  26  Several files (gc/gc_allocator.h, extra/msvc_dbg.c) come with slightly
  27  different licenses, though they are all similar in spirit (the exact
  28  licensing terms are given at the beginning of the corresponding source file).
  29  
  30  A few of the files needed to use the GNU-style build procedure come with
  31  a modified GPL license that appears not to significantly restrict use of
  32  the collector, though use of those files for a purpose other than building
  33  the collector may require the resulting code to be covered by the GPL.
