Subject: [PATCH 112/112] Workaround broken GCC 15

The C++ standard does not allow 'alignas' to be applied to type
|
|
aliases. GNU C++ has allowed it as a non-standard extension, but
|
|
strictly that should have been expressed using 'gnu::aligned'
|
|
instead of 'alignas'. Regardless of the syntax, however, GCC 15
|
|
has a regression causing it to reject alignment requests entirely
|
|
on template aliases.
