The current maintainer does not have access to these systems, and assumes that
the system is at least Single-Unix-Specification V3 compatible, and that
-will also require a C99 compiler.
+will also require a C99 compiler. A further requirement is that
+either realpath() permits its 2nd argument to be NULL for auto-allocation,
+or that otherwise PATH_MAX be defined.
Fetchmail should be able to be compiled with C99, C11, C++98, C++03,
C++11, C++14 compilers, but not C++17 because the "register" keyword is
used in some parts of the code.
+Future fetchmail releases will require modern language features such as
+"long long" and others, so this release is the last to support C89.
