# Minimalist, stripped down, w64devkit, static, unity build of Boehm GC.
# Provides an easy-to-use garbage collector weighing ~24KiB. The API is
# two functions: GC_malloc and GC_realloc. Tested with gc 8.2.4.
#
# Place this source file in the Boehm GC source tree root, then invoke
# it with the shell to produce gc.h and libgc.a.
#
#     $ sh libgc.c
#
# Philosophy: If the goal is ease-of-use, remove all knobs that are not
# strictly necessary. If performance isn't good enough, don't use garbage
# collection; switch to a region-based allocator.
#
# Ref: https://www.hboehm.info/gc/gc_source/gc-8.2.4.tar.gz
# This is free and unencumbered software released into the public domain.
