Building ROOT on AIX with egcs...

Hello ROOTers.

Has anyone had any success building ROOT on AIX 4.2 with egcs?  I have
been unable to find much of anything on the subject in the ROOTtalk
archives or anywhere on the ROOT website.  I've found binaries for AIX
4.1 (Much earlier version of ROOT), and for AIX 4.3 (ROOT version 2.22 -
comment says ONLY WORKS ON AIX 4.3).  I used the binaries for AIX 4.3
and the .aixegcs makefile.  After doing a gmake distclean I tried to
build the whole thing.  

I had to change the LD variable from " LD = makeSharedLib " to " LD =
g++ " and add " -Xlinker -G " to the SOFLAGS variable in
Makefile.aixegcs.  With these mods I get to the point where rootcint is
invoked on the sources.  Here I get an error stating that the library
dl.o cannot be found.  I have a library called dl.a, but none called
dl.o.  

Can anyone offer advice on building ROOT under AIX (specifically version
4.2)?

Also, a question for the developers.  Why is the Makefile that is
provided "Only for AIX 4.3"?

Regards,
Dan.
