Subject: md5: supress some compiler warnings.
X-Git-Tag: 11.0.0-beta1~375
X-Git-Url: http://git.asterisk.org/gitweb/?p=asterisk%2Fasterisk.git;a=commitdiff_plain;h=19097a4b62860092f1dc70a42f07103c0586aed1;ds=sidebyside

md5: supress some compiler warnings.

md5.c: In function ‘MD5Final’:
md5.c:154:2: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing]
md5.c:155:2: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing]

There is an md5 unit test and it still passes.
