MySQL finally finally fixed the bug that prevented php 5 from compiling cleanly on OSX when compiling with MySQL headers.
YAY!
Today I downloaded 5.0.37 and 5.2.1 php. Installed mysql and started to compile php, pretty much expecting it to fail, as it has since it was broken October of last year.
Worked!
Threads is running on it just fine, no errors, no problems.
