20dnl
21dnl The UW-IMAP c-client library was not originally designed to be a
22dnl shared library. The mm_foo functions are callbacks, and are required
23dnl to be implemented by the program that is linking to c-client. This
24dnl macro does the work of defining them all to no-ops for you. Note
25dnl that PHP_TEST_BUILD is a link test; the undefined symbols will only
26dnl cause problems if you actually try to link with c-client. For
27dnl example, if your test is trivial enough to be optimized out, and if
28dnl you link with --as-needed, the test/library may be omitted entirely
29dnl from the final executable. In that case linking will of course
30dnl succeed, but your luck won't necessarily apply at lower optimization
31dnl levels or systems where --as-needed is not used.
