Hi,

This patch:

2022-05-25 2022-06-01 b251bb7630  eal/ppc: undefine AltiVec keyword
vector      @Thomas Monjalon

Looks like an incompatible change? Commit message says so too:

"This is a compatibility breakage for applications which were using
the keyword "vector" for its AltiVec meaning."

The first one looks like but I don't think we should pick up the
second one for the LTS branches?

Kind regards,
Luca Boccassi
