32-bit i386-pc-solaris2.11 cons-cons.ii
Between 20230329 (b2f327b9be81326c9e59fc6da98074c909ac7408) and 20230330
(a23b33a1bdeff7bc2289d9ebb7cb7b7ec0a605f5), the
experimental/net/internet/endpoint/cons.cc test began to FAIL on Solaris
(11.3 and 11.4, SPARC and x86):
+FAIL: experimental/net/internet/endpoint/cons.cc (test for excess errors)
+UNRESOLVED: experimental/net/internet/endpoint/cons.cc compilation failed to
produce executable
The log shows
Excess errors:

error: non-constant condition for static assertion
/vol/gcc/src/hg/master/local/libstdc++-v3/testsuite/experimental/net/internet/endpoint/cons.cc:78:
error: accessing 'in_addr::<unnamed union>::S_addr' member instead of

The full message is

This is no doubt due to

libstdc++: Fix constexpr functions in <experimental/internet>
but I don't know what's going on. I'm attaching the preprocessed testcase.
