macports standard builds on 10.6.8 build just fine, both 32&64 bit

Yes, thank you, I just updated ports and checked it on 10.6.8 x86_64. Likely gonna fail on Leopard PPC too. Cannot check right now.

UPD. gcc12 builds it fine on Rosetta.

Preferable to try make it compile with gcc-4.2 rather than blacklisting it for platform powerpc?

[kencu (Ken)]

it’s possible it may not build with gcc-4.2 on any platform in any arch… have to do some checking to know for sure.

I confirmed it to build with gcc-4.2 for x86_64 on 10.6.8. Let me try for i386.

UPD. It fails for i386. Let us blacklist *gcc-4.* on 32-bit platforms.

[kencu (Ken)]

Or just blacklist *gcc-3.* *gcc-4.* on all systems all the time, for consistency. Sure, that sounds like a fine PR.

tinyxml2: blacklist compilers which fail to build consistently (​https://github.com/macports/macports-ports/pull/16560)

very old compilers fail to build this for some arches, notably 32bit.
