24 25 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.
