This is not the right way to do it - this would link in dead duplicates
of the code into the embperl shared object, possibly creating duplicate
global variables only visible in the embperl object that are not the
same as the ones used in the Apache main httpd executable. You must use
proper .exp files to signal the linker that the symbols are to be
imported at runtime from some other shared object.

It is not buggy, it is just very different. Most unix linkers consider
global variables from all shared objects that comprise a process image
as one global space. The AIX linker does not do that, it does
explicitely require you to specify which global symbols enter the
inter-module name space through the use of .exp files. If you link in
global symbols from some .o files these are not global symbols for other
shared objects unless being made inter-module global by an .exp file.
