What steps will reproduce the problem?

1. Checkout the latest code from the git repository @ https://code.google.com/p/gperftools/
2. run autogen.sh script
3. run configure script
4. do make. 

What is the expected output? What do you see instead?

Expect output would be a clean compilation. Instead one gets the following error: 

clang++ -DHAVE_CONFIG_H -I. -I./src  -I./src   -D_THREAD_SAFE  -Wall -Wwrite-strings
-Woverloaded-virtual -Wno-sign-compare -fno-builtin-malloc -fno-builtin-free -fno-builtin-realloc

What version of the product are you using? On what operating system?

checkout of master branch @ e7297f0c14b0c09ec52707ed7477c7aee43a1882, using Mac OS
X 10.9.2

Please provide any additional information below.

the commit a2375a1f360c0451ec2a2b852ea26a71fb731727 introduces malloc.h header file
on src/tests/debugallocation_test.cc in order to use memalign. I removed the include
of malloc.h and compilation went through. But it seems that malloc.h has been deprecated
on mac os and freebsd ( i guess ) .. and a patch like this would probably make sense(?):
