When compiling Perl, you must use an ANSI C compiler. AIX does not ship
an ANSI compliant C-compiler with AIX by default, but binary builds of

AIX supports dynamically loadable objects as well as shared libraries.
Shared libraries by convention end with the suffix .a, which is a bit
misleading, as an archive can contain static as well as dynamic members.
