Crash in triangle-test when building w/o acute

[jzarl]

When building without acute, I get the following segfault when executing triangle-test:

(gdb) run
Starting program: /home/zing/Projects/femm/Triangle/src/build/examples/triangle-test/triangle-test 
OK: test_context_create_destroy
OK: test_behavior_parse

Program received signal SIGSEGV, Segmentation fault.

Note: in order to pass test_behavior_parse I commented out the following line from tests.c:

    result &= (b->maxangle == 100.0); // line 41

This is because the NO_ACUTE flag isn't set for the executable projects and so the behavior and mesh structs get messed up.

A fix would either be to define the flag for all projects, or remove the #ifndef NO_ACUTE from the structure definitions.

You're right - I've fixed my build to set NO_ACUTE properly in all places and the problem is gone now…
