Problems using gcc 3.0 and 3.0.1 on RedHat 7.0

[Bill Bland]

Hello,
	I successfully compiled and installed gcc 3.0 and 3.0.1 (not at
the same time!) on my i586 RH7.0 box.  AFAICS I followed the instructions
to the letter (built in a separate directory to the source, etc).
The java and c compilers work fine.  Unfortunately when compiling any c++
code that contains the "new" and/or "delete" operators I get link warnings
of the form:

	undefined reference to `operator new(unsigned)'

I thought that this could be a problem with the linker, ld, so I
compiled and installed the latest binutils which changed
nothing.  Re-installing the gcc rpms that come with RH7 makes it all work
again, so it's not a problem with the c++ that I'm trying to compile (it's
fltk for the record).  But obviously I don't want to do this - I want
gcc3 ;-)
Has anyone seen anything like this before?  Anyone know how to solve it?

Best wishes and thanks in advance,
		Bill.
