Re: [Gcl-devel] 2.6.2

[Camm Maguire]

Greetings!

Mike, these compiler/binutils dependencies are most likely indicating
that we still have a problem in the linker, unless it is typical for
mingw/msys programs to behave this way.  At some point, we  need to
get a test case with the smallest .o file possible, and objdump -d
and objdump -x them.  Post 2.6.2 of course.

Yake care,
