dlmalloc.c: Fix gcc alias warning
Fix these warnings: dlmalloc.c: In function 'free': dlmalloc.c:2507: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2507: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2507: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules Some page(http://blog.worldofcoding.com/2010/02/solving-gcc-44-strict-aliasing-problems.html) suggests adding __attribute__((__may_alias__)). Doing so makes the warnings go away. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> Acked-by: Mike Frysinger <vapier@gentoo.org>
