+Subject: [PATCH] Fix bad prototype for malloc() in test
+
+The unit test Gtest-nomalloc.c had an incorrect prototype for malloc()
+which caused newer compilers to fail compiling for newer C editions.
+
+Corrected the prototype and corrected a few other errors. The unit now
+compiles using GCC with `CFLAGS=-Wall -Wextra -pedantic -C11` with no
+warnings, which is the minimum requirement.
+
+Added the tests/unw_test.h header as a first step to cleaning up some
+unit tests further.
