[Nix-dev] Tmux-1.9a fails to build in Yosemite

[Alfredo Di Napoli]

Hello Nixers,

installing tmux-1.9a (latest) on a fresh Yosemite machine fails with:

gcc -DHAVE_CONFIG_H -I. -I..  -I.. -I../compat -I../include -I../include
-DTINYTEST_LOCAL -D_THREAD_SAFE     -g -O2 -Wall -fno-strict-aliasing
-Wno-deprecated-declarations -D_THREAD_SAFE  -c -o regress-tinytest.o `test
-f 'tinytest.c' || echo './'`tinytest.c

Who is to blame, Apple or the tmux source code? (from a quick glance seems
the former)
Thanks!
