Re: Building: alloc.c:766:1: error: negative width in bit-field `_gl_verify_error_if_negative'

Your compilation environment appears to have a problem, in this part of
config.log:

You probably need to fix this, for other reasons.  But before you fix it,
could you please see whether the following patch avoids the static assertion failure?
Thanks.
