+       Compatibility: recent Linux distributions have C compilers
+       with a built-in 'bool' type (size=1) that conflicts with
+       Postfix's bool (an alias for int, typically size=4). Postfix
+       3.11 adopts the built-in bool type, but that change is too
+       large for the stable releases. Instead, the command "make
+       makefiles" will figure out how to make the compiler
+       backwards-compatible. File: makedefs.
