+Subject: [PATCH 3/4] NO_FORK: control usage of fork() for nommu systems
+
+nommu systems lack a fork() function, so add a NO_FORK flag to control
+its usage. We don't lose a ton of functionality in doing so, and on an
+embedded system, this is OK.

+Subject: [PATCH 4/4] NO_PERROR: control overriding of perror() symbol
+
+Doing static builds of portmap might fail when the C library's perror()
+function is pulled in and collides with portmap's definition. So add a
+flag to control the local override.
