No, it is from the libexec/httpd.exp file from Apache.

Well, it is not supported under previous versions of AIX. It means that
the symbols come from the main executable, this is httpd in our case
here. I do not think that this is a problem, although I do not have it
in my build here as I had to delete the "." from the httpd.exp file as I
also used the same Apache tree to build under AIX 4.1.5 which does not
support the "." notation. If the dlopen emulation layer is used (one of
our first excercises was to ensure this) than symbols without any import
ID (noIMid in the dump output) will be resolved by the explicit loadbind
calls made inside the dlopen function.
