Yes, that's correct. The current (as of 2019-12-19) GCC 9.2.1 offering is based on musl 1.1.24, though the 7.5.0 release is using a more recent git tag only due to timing/availability. Within reason, I'm happy to bump versions with justification. Rebuilding takes about a full day but no time on my end. Rich sent out a message [1] just today suggesting there is still some time64 work to be done, so once he pushes those patches I'll build and release new toolchains for 9.2, 8.3, and 7.5.
