Hi Jim,
: Actually, we need to add the -L option to every line in CXX_FOR_TARGET
: that uses g++ from the build tree. Not just the non-newlib case. This
: was just a quick hack to get Syd going. I mentioned that the patch was
: incomplete, but he apparently didn't pass that along.
Ah, thanks - I have attached a modified patch below. I assume that
this version is what you had in mind ?
Shall I check this version in ?
Cheers
Nick

* Makefile.in (CXX_FOR_TARGET): Add libstdc++ to the library
search path for a g++ extracted from the build tree. This
will allow link tests run by configure scripts in
subdirectories to succeed.
