Quick question:

Would these functions be available in both the static and dynamic
versions of libc?

Here's my issue (and perhaps it doesn't apply here):

At my job I'm responsible for the Apache builds (+mod_ssl,+perl, +custom
afs client code, etc etc). I like to do the builds static because it makes
lots of things easier (on HP-UX: debugging, debugging, more debugging,
and the usual benefits of static linking. Solaris also). 

I'm annoyed that I can't get a totally static build because of dl*
functions in some library (I can't remember offhand, and I link in
something like 20 libraries...). I have to pull schenanegans to
get my servers to build with this motley list of libraries, giving
flags to cut static/dynamic linking on/off, in order to get a build.

I mean, really now, should this be in a build:
-lc -lBSD -Wl,dynamic -lc -Wl,static

That's gross. (libBSD on HP-UX pulls in compat functions needed by AFS,
but I have to link libc in first so things like stat() aren't subverted.)

I hate it when static and dynamic versions of libraries have different

I hope this sort of thing won't be an issue in NetBSD.
