Originally reported on Google Code with ID 530

What steps will reproduce the problem?
1. Create VirtualBox VM with Ubuntu guest
2. Share any folder using VirtualBox
3. Try to compile gperftools

What is the expected output? What do you see instead?
gperftools should successfully compile. However, it doesn't as it cannot find mmap,
which is required.

What version of the product are you using? On what operating system?
gperftools-2.0, Ubuntu 12.04 32bit

Please provide any additional information below.

Shared folders use special VirtualBox filesystem, which doesn't support mmap. See related
VirtualBox issue - https://www.virtualbox.org/ticket/819. It should probably reproduce
on any other filesystem without mmap.

Originally, I asked this question in Google group and was pointed to raise issue. See
https://groups.google.com/forum/?fromgroups=#!topic/google-perftools/5O7pyQ-xXmk for
(short) discussion.

Truncated logs are attached.

I've looked at this issue closely.

It appears that AC_FUNC_MMAP is testing if source directly filesystem supports mmap.

We could potentially do something about it but IMHO it's not worth it.

Just don't build gperftools on such filesystems.
