[tor/master] Add a --with-malloc option.

commit abde9fb426c7d6d0dbdaccc724c3b4257d99ad30 Author: Nick Mathewson <nickm(a)torproject.org> Date: Wed Jul 11 09:28:23 2018 -0400 Add a --with-malloc option. Based on a patch from Hello71 on ticket 20424. This patch additionally fixes openbsd-malloc support, switches our tcmalloc support to use pkgconfig, and tells the compiler to omit system malloc implementations as appropriate. squash! Add a --with-malloc option. Edit changelog file to fix a typo and credit Alex Xu in preferred format. --- changes/ticket20424 | 5 ++++ configure.ac | 71 ++++++++++++++++++++++++++++++++++++++++++++--------- 2 files changed, 65 insertions(+), 11 deletions(-) diff --git a/changes/ticket20424 b/changes/ticket20424 new file mode 100644 index 000000000..123807ae2 --- /dev/null +++ b/changes/ticket20424 @@ -0,0 +1,5 @@ + o Minor features (compilation): + - Tor's configure script now supports a --with-malloc= option to select + your malloc implementation.
