+/*
+** Stubs for nspr_symvec.opt
+**
+** PR_ResumeSet, PR_ResumeTest, and PR_SuspendAllSuspended
+** (defined in ptthread.c) used to be exported by mistake
+** (because they look like public functions).  They have been
+** converted into static functions.
+**
+** There is an existing third-party binary that uses NSPR: the
+** Java plugin for Mozilla.  Because it is part of the Java
+** SDK, we have no control over its releases.  So we need these
+** stub functions to occupy the slots that used to be occupied
+** by PR_ResumeSet, PR_ResumeTest, and PR_SuspendAllSuspended
+** in the symbol vector so that LIBNSPR4 is backward compatible.
+**
+** The Java plugin was also using PR_CreateThread which we didn't
+** realise and hadn't "nailed down". So we now need to nail it down
+** to its Mozilla 1.1 position and have to insert 51 additional stubs
+** in order to achive this (stubs 4-54).
+**
+** Over time some of these stubs will get reused by new symbols.
+**   - Stub54 is replaced by LL_MaxUint
