[ECOS] g++ problem resolving '__builtin_delete' in cross compilation/linkage

[John Mills <Jmills@TGA.com>]

I built a partial set of ecosSWtools-990319 targeting the SH-2 from a
Linux/RH6.0 installation which appears to compile and link properly for
simple 'C' source. Moving to 'C++', I also get executables which map
properly to my target board, and better yet, produce debug data sufficient
for an Hitachi debugger to step through the code from source level.

When I link, I have an undefined reference to '__builtin_delete' at exit
where the C++ object is deleted. (I have no actual destructor nor
dynamically allocated storage for the simple example.) If I simply edit the
assembly language and remove the call to '__builtin_delete' the code links
and runs fine.

I looked through my provisional libs, and those for the established
mips-tx39-elf target, without finding where this might have arisen and
should be resolved. There is a remark in 'gcc/Changelog.egcs', on Nov 20,
1997, to the effect:

"* libgcc2.c: Remove __builtin_new, [...], __builtin_delete, and [...]."

Can anyone suggest what I need to provide here? Thanks.
