Re: [PHP-DEV] [PHP4] Problem with old versions of 'ar' From: Jim Jagielski (jim <email protected>)

But that doesn't help at all if the underlaying compiler, and more
importantly the loader, does not support the new archive
structure. You can't simply install GNU ar and have your system 'ld'
parse the new archive. And there are many, many legacy systems
out there that have gcc installed, but it's 'ld' implementation
is simply collect.

It's certainly a valid argument saying that PHP4 doesn't support
the legacy systems that worked just fine with PHP3. If that's
the decision, then that's it.
