php-src/ext/standard/syslog.c
Stig Bakken 257de2bade First commit of re-structuring phase one. We have started using automake in 
sub-directories and started to move extension code into ext/<name>.  For now,
I have moved the "standard" extension (which is quite a mix of everything
right now) and the GD extension into their own subdirs in ext/.
The configure script now also runs configure in the libzend directory
automatically and makes sure php4 and libzend use the same config.cache file.
To avoid running configure in libzend, use the --no-recursion option.
"make" in php4 also builds libzend now.
The Apache module doesn't compile right now, but a fix for that is
coming up.
