Subject: macros to create usual functions : new/delete and init/wipe.
X-Git-Url: http://git.madism.org/?p=apps%2Fmadmutt.git;a=commitdiff_plain;h=344312314eec327c3bf47f86950a5ad6c616e031

macros to create usual functions : new/delete and init/wipe.
we will use __attribute__ so add the define so that it compiles on other
compilers well
