commit    451650eaacd5e482380f2b0e506fc81f5aa92fc7
Author:   Peter Eisentraut <peter@eisentraut.org>
Date:     Tue Feb 17 09:06:39 2026 +0000

    Test most StaticAssert macros in C++ extensions
    
    Most of the StaticAssert macros already worked in C++ with Clang and
    GCC:(the only compilers we're currently testing C++ extension support
    for).  This adds a regression test for them in our test C++ extension,
    so we can safely change their implementation without accidentally
    breaking C++.
    
    The only macros that StaticAssert macros that don't work yet are the
    StaticAssertVariableIsOfType and StaticAssertVariableIsOfTypeMacro.
    These will be added in a follow-on commit.
