svn commit: r204025 - head/share/mk

New Revision: 204025
URL: http://svn.freebsd.org/changeset/base/204025

Log:
  Allow suppression of -Wcast-align for WARNS>=4 by defining
  NO_WCAST_ALIGN. The headers of the standard C++ library are
  not 64-bit clean and trigger the warning. This prevents use
  of WARNS>=4 on ia64 for example.
