David,
This patch has broken the top-of-tree glibc build. I get an error on an
undef that is supposed to be protected by Pragmas. It happens when
compiling intl/plural.c in glibc. I created a preprocessed source file
but when I compile it, the error doesn't happen. I will try to create a
small unpreprocessed standalone test case but maybe this is enough for
you to know what is happening.
If I look at the preprocessed code, the statement in question is
under ingore warning pragmas.
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wuninitialized"
#pragma GCC diagnostic ignored "-Wmaybe-uninitialized"
*++yyvsp = __gettextlval;
#pragma GCC diagnostic pop
