[Lazarus] Request for merge to 2.0

[Martok]

Dear maintainers,

may I ask to merge rev 62042 into fixes_2_0 for the next patch release?

This change from 2019 fixed building Lazarus with sparta_DockedFormEditor (see
#34899), which is still broken in 2.0.10.

Juha mentioned in #37968 that the sparta_Generics package will go away once 3.2
is the minimum requirement, but r62042 solves the issue for new FPC while
keeping compat with old. And since the official Windows installers come bundled
with FPC 3.2, the bug occurs with the current distribution.


Thanks,

Martok
