* However, GCC didn't support that for function *pointers* until GCC
* 4.1.0; see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3481.
* XL C 16.1 (and possibly some earlier versions, but not 12.1 or 13.1) has
- * a similar bug, a bugfix for which should be available later:
- * https://www.ibm.com/support/pages/apar/LI81402
+ * a similar bug, the bugfix for which was made in:
+ * * version 16.1.1.8 for Linux (25 June 2020), which fixes
+ * https://www.ibm.com/support/pages/apar/LI81402
+ * * version 16.1.0.5 for AIX (5 May 2020), which fixes
+ * https://www.ibm.com/support/pages/apar/IJ24678
+ *
+ * When testing versions, keep in mind that XL C 16.1 pretends to be both
+ * GCC 4.2 and Clang 4.0 at once.
