PHP 5.3.6 released with changes for Windows users :VC++6 builds disabled
Officially VC++6 builds are dead (There are community builds but unsupported by core php developers)
Here is the announcement
Windows users: please mind that we do no longer provide builds created with Visual Studio C++ 6. It is impossible to maintain a high quality and safe build of PHP for Windows using this unmaintained compiler.
For Apache SAPIs (php5_apache2_2.dll), be sure that you use a Visual Studio C++ 9 version of Apache. We recommend the PHP builds as provided by ApacheLounge. For any other SAPI (CLI, FastCGI via mod_fcgi, FastCGI with IIS or other FastCGI capable server), everything works as before.Third party extension providers must rebuild their extensions to make them compatible and loadable with the Visual Studio C++9 builds that we no longer provide.

Firebird internals : Asyncronous System Trap
What is Asyncronous System Trap ? : This is similar to Unixes signal’s or OS interrupts.
Technically this is callbacks from Lock Manager into the Engine called when
somebody acquires lock at level not compatible with current level. In this case
all processes who owns the lock receives notification and should take appropriate
action to release lock (immediately or deferred-ASAP).
The main trick with AST’s handlers is that AST is send asynchronously and
handler must take care to work correctly. Since v2.5 all ATS handlers runs in
separate thread. Before v2.5 it works using signals on Unixes and threads on
Windows.
PS the issue with old glibc and FB 2.5 is that since v2.5 we abandoned usage of old
System V semaphores (do you remember “semaphores are exhausted” error ? now
you can forget it completely) and start to use pthread mutexes. And old glibc have a
bugs in pthread mutex implementation.
Extracting glibc info in #Linux to see if is greater or equal with 2.7
Related to previous announcement:If you are on ubuntu and your ubuntu release is greater than Hardy (8.04) you are safe , on other distributions you can determine this way the glibc version
You must run the /lib/libc.so.6 and it will return the glibc version
in the first row.
In ubuntu or any debian based distro
/lib/libc.so.6 | head -n 1
GNU C Library (Ubuntu EGLIBC 2.13-0ubuntu1) stable release version
2.13, by Roland McGrath et al.
in this case glibc is 2.13
and is builded from eglibc sources
https://launchpad.net/ubuntu/+source/eglibc
another option is dpkg interrogation
dpkg -l libc6
on rpm based distros
rpm -q glibc
ps: other alternative ways

Stefan has improved the Windows support also fixed many tests , here are some of the commit messages:
Improved support for MinGW, added support for ActivePerl, Removed some obsolete tests, All tests, now use testlib.pl and Test::More (except 60leaks.t)

From Oracle to FireBird – a comparison of functions
We have made an comparison of functions between Oracle and FireBird to avoid the nice (but incomplete) UDF-library UDF4Ora. Most of the Oracle functions are similar to FireBird- or FreeAdhocUDF-functions. Here you find a complete liste of comparison.
If you are interested in one (or more) not presented functions send an eMail to help@freeadhocudf.org.
