zlib +universal requires -mmacosx-version-min=10.4

[gui-dos (Guido Soranzio)]

When not adding to the zlib's portfile the line

configure.universal_cflags-append -mmacosx-version-min=10.4

the compilation fails reporting the error:

What version of Mac OS X, MacPorts and Xcode do you have and what kind of processor is in your Mac?

MacPorts trunk already includes -mmacosx-version-min=whatever when running on Leopard. See r33480.

I'm running Mac OS X 10.4.11 with Xcode 3.0 and MacPorts trunk on Intel, but I have never seen this error with previous MacPorts versions either.

As I reported, I am referring to MacPorts 1.7.0 from trunk.

I am trying to rebuild from scratch all the universal variants on a G4 with Leopard 10.5.2. The other ports are seeing the extended LDFLAGS but the "gcc-4.0 -dynamiclib" of zlib isn't using them and you have to modify the CFLAGS in order to enforce passing "-mmacosx-version-min=10.4" to it.

The same issue happens with jpeg:

Instead of modifying the configure/makefile scripts, we could simply add

configure.universal_cflags-append -mmacosx-version-min=10.4

in the configure_get_universal_cflags proc of portconfigure.tcl, too
