No we won't have both libraries. The boxes will be sent to customers
with uClibc as the libraries.

Yes

The stuff we send out uses shared libraries and is cross-compiled on
another machine. The customers may or may not do things statically.

Linux 2.4.18

I don't think this will work. I need the standard libraries there to
run the existing compiler. This is an embedded system with only 8Mb
set aside for OS stuff. I don't have the space for two versions of
the libraries.

Like the above case the current compiler uses shared objects and so
will anything it generates unless I can figure out how to force it
to be static.

I understand all that. The compiler I want to build needs to be linked
against uClibc so that when it runs it doesn't look in /lib for libc-2.2.5.so
and so on. I don't know if there is an option to configure to tell it how
to do this. I suppose I could do a configure and then edit the Makefiles to
do statically link against the uClibc files but that is also something I'm
not 100% sure how to do.
