I ran into this problem when building GNU m4 (Savannah commit 7d5125b78d56dfa08b6bb4205428eb9962ad9244) on Solaris 10 sparc. It has GCC 3.4.3 (csl-sol210-3_4-branch+sol_rpath), which lacks _Static_assert. GNU m4 both uses assert-h and includes <verify.h>, and without this patch the latter mistakenly #undefs the _Static_assert that the former defined. * lib/verify.h (_Static_assert) [_GL_STATIC_ASSERT]: Do not undef. --- ChangeLog | 11 +++++++++++ lib/verify.h | 5 +++-- 2 files changed, 14 insertions(+), 2 deletions(-)
