Further tests worked out well, so libgd can now easily built with Visual
Studio 2015: <https://github.com/libgd/libgd/tree/master/windows>.

Thanks!

The sources for PECL libs are taken from the respective public sources and in most case it's built as is or with a minimal change for lib names, etc. Usually also they're built just once for the given compiler, except asked by someone to upgrade.

Thanks for the info. :)

> Yeah, that's fine. I was doing libjpeg-turbo for the gnome libs, as it's now recommended for gnome in favor of classic libjpeg. The libs would collide in PHP otherwise, as we use the classic libjpeg in the core. Doesn't matter functionally, but otherwise what I've seen, is that libjpeg-turbo has a lot of ASM optimization. As it only implements a subset of the classic libjpeg, would probably have to be thoroughly checked, but otherwise it could outperform the classic one on x86 architectures.

Would be interesting to do some performance comparisons, but I'm afraid
I won't find time for that in the near future.
