Go flop. The first issue is a built RedBoot (4.6.2) could not assist to
run built eCos tests (4.6.2) under GDB (7.3.1). I have no ideas what was
wrong with that as the same RedBoot sources are built with (GCC-4.3.2)
provide GDB support for new eCos tests (built with GCC-4.6.2) in GDB
7.3.1, and the second issue is that the build tests (with GDB-4.6.2) had
.text segments more bloat (1.1 ~ 1.2) than the same builds are built
with GCC-4.3.2. Though one patch was applied to config/i386/i386elf.h

It seems to me that I cannot propose to s/4.3.2/4.6.2/ for i386 :-( BTW,
mpfr/mpc/gmp versions were not an issue (I had the same results with the
newest libraries and with stable ones).
