Somehow it's c++ headers (like string) define pthread symbols without
even us asking for. That breaks old assumption that pthread symbols
are not available on windows.
In order to fix that we detect this condition in configure.ac and
avoid defining windows versions of pthread symbols.
Some people might want to check-in unpacked result on make dist into
git. But because git doesn't preserve timestamps it would cause those
automatic "auto-retool" rules to trigger. Sometimes even causing build
breakage if system's autotools version don't match autotools version
used for make dist.
Easiest way around this problem is to simply disable those unnecessary
"maintainer" rebuild rules. Especially given that source is always
freely available via git and therefore there should be no reason to
regenerate any of autotools products in 'make dist'-produced sources.
Because it was found that __thread variables access is compiled into
calls to tlv_get_addr which was found to call malloc. Because we
actually use thread-local storage from inside malloc it leads to stack
overflow. So we'll continue using pthreads API for that which is known
to work on OSX.
I.e. we have to check their presence in configure and in case of their
presence we have to avoid re-defining then in window's port.h

So that it's easier to contribute and review contributions.
People wishing to build gperftools from svn checkout should run
autogen.sh first which will create those files and then ./configure &&
make as usual
INSTALL file has updated instructions too.

tcmalloc contained a bug where some internal locks were left in a undefined state
between fork, leaving the child process in a deadlock state. This patch fixes the
issue by introducing stricter locking between the parent nd child while forking.

Previously __builtin_ expect was based on a macro check against gcc version.
Now we perform the check via AM which is a cleaner approach. There are also
a number of code changes here to utilize LIKELY/UNLIKELY macros based on
__builtin_expect to improve performance.

- Used aclocal, autoupdate, autoconf, and automake to correctly apply changes made to Makefile.am. Detailed instructions on this procedure can be found here http://inti.sourceforge.net/tutorial/libinti/autotoolsproject.html.
- Fixed a number of error/warning messages due to use of newer aclocal, autoconf, and automake utilities.
- Directly and indirectly related to issue-385 and issue-480.

In revisions 151 and 150 an attempt was made to enable frame pointers by default for i386. However, in the process of doing so a number of files were inadvertently touched as a result of running autogen.sh. As a result, I have needed to roll back these revisions so that I can reattempt the change.
