+Subject: [PATCH] Fix crash in var_defines when define string is empty (#535)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+* Fix crash in var_defines when define string is empty
+
+b2 aborts in var_defines on empty define
+
+* Redo no-value error fix to keep previous flow.
+
+Still avoid errors for empty variables, but do so while not early continue, and to keep the use of string_view.
