+== TODO tasks ==
+
+tests/CMakeLists.txt: Add more executables (see tests.am).
+
+Use C++0x ATM (atomic memory operations) if available (either from the
+compiler runtime, provided it is reliable, or from the future libatomic_ops).
+
+Add a test for libatomic_ops minimal version required (at compile time).
+
+windows-untested: Remove if CMake can generate MS Visual Studio 6.0, 7.0, 8.0
+project files.
+
+BCC_MAKEFILE: Remove if CMake can generate Makefile for this compiler.
+(Same for WCC_MAKEFILE, OS2_MAKEFILE, NT_MAKEFILE, NT_STATIC_THREADS_MAKEFILE,
+NT_X64_STATIC_THREADS_MAKEFILE, NT_X64_THREADS_MAKEFILE, digimars.mak,
+gc.mak.)
+
+Makefile.dj: Remove if it is possible to use Makefile.direct (or
+auto-generated Makefile) instead. (Same for EMX_MAKEFILE.)
+
+build_atomic_ops.sh[.cygwin]: Remove if really not needed.
+
+BCC_MAKEFILE, EMX_MAKEFILE, OS2_MAKEFILE, PCR-Makefile, WCC_MAKEFILE,
+SMakefile.amiga, Makefile.dj, digimars.mak: move to "build" folder.
+
+Do type-punning via union (instead of pointer type cast) to enable safe
+'-fstrict-aliasing' compiler optimization option.
+
+Support CAN_HANDLE_FORK if USE_WINALLOC for Cygwin.
+
+Enable GC_set_handle_fork(1) for Darwin with GC_dirty_maintained on (both
+single and multi-threaded modes).
+
+Add more fields to GC_prof_stats_s (potential candidates are:
+requested_heapsize, max_large_allocd_bytes, large_allocd_bytes, bytes_dropped,
+bytes_finalized, bytes_freed, finalizer_bytes_freed, composite_in_use,
+atomic_in_use, GC_n_heap_sects, GC_n_memory, GC_black_list_spacing,
+GC_root_size, GC_max_root_size, n_root_sets, GC_total_stacksize,
+GC_collect_at_heapsize, GC_fail_count, GC_mark_stack_size, last_fo_entries,
+last_bytes_finalized, last_finalizer_notification_no, GC_dl_entries,
+GC_old_dl_entries, GC_used_heap_size_after_full, GC_total_stack_black_listed,
+signed_log_dl_table_size, GC_n_rescuing_pages, signed_log_fo_table_size,
+GC_excl_table_entries, GC_stack_last_cleared, GC_bytes_allocd_at_reset,
+GC_n_heap_bases, registered_threads_cnt, GC_max_thread_index, GC_block_count,
+GC_unlocked_count, GC_hdr_cache_hits, GC_hdr_cache_misses, GC_spin_count).

+
+== FIXME tasks ==
+
+Solaris + GCC: make check fails with the message:
+libc.so.1: gctest: fatal: libgcc_s.so.1: open failed: No such file or directory
+
+Solaris/x86[_64]: gctest fails if PROC_VDB.
+
+Darwin/x86_64: deadlock might occur between:
+dlclose() -> GC_dyld_image_remove() -> GC_lock() and
+GC_inner_start_routine()+LOCK -> dyld_stub_binder_().
+
+HP-UX 11.00 with the vendor cc fails:
+Perhaps GC_push_regs was configured incorrectly? FAIL: gctest.
+
+FreeBSD 9.0/x86_64 (gcc-4.2.1-20070831): gctest segfaults sometimes in
+GC_typed_mark_proc if configured with --enable-threads=pthreads.
+
+OpenBSD 5.1/i386: leaktest fails rarely (unless logging redirected to file):
+cannot write to stderr from GC_gcollect invoked from 'atexit' hook.
+
+NetBSD 5.1/x86: threadkey_test hangs sometimes.
+
+Cygwin: subthread_create: exception STATUS_ACCESS_VIOLATION.
+
+Cygwin: gctest: assertion failure at UNLOCK in GC_fork_parent_proc.
+
+Sun C++ 5.11: test_cpp.cc:237: Error: Too few arguments in call to
+"operator delete(void*, GCPlacement, extern "C" void(*)(void*,void*), void*)".
