I may have though `configure` erroneously transmitted the exception API
option, but that's not just that, that's also inconsistent.
`libgcc_s` is built with a mixture of SJLJ and ZCX exception API, and `cc1`
is built to expect ZCX exception API.
Here is the error with which the build terminates:
libppl_c.so: undefined reference to `_Unwind_Resume@GCC_3.0'
libstdc++.so.6: undefined reference to
`_Unwind_Resume_or_Rethrow@GCC_3.3'
libstdc++.so.6: undefined reference to `_Unwind_RaiseException@GCC_3.0'
Here is what was built in `libgcc_s`:
$ nm -D build/prev-gcc/libgcc_s.so.1 | grep _Unwind_
00015d44 T _Unwind_Backtrace
00015d24 T _Unwind_DeleteException

00015c9c T _Unwind_SjLj_Resume_or_Rethrow
000158d8 T _Unwind_SjLj_Unregister
There's an inconsistency.
Configuration was run as:
../source/configure \
--build=i386-linux-gnu \
--disable-build-with-cxx \
--disable-coverage \
--disable-gather-detailed-mem-stats \
--disable-gc-debug \
--disable-gnu-unique-object \
--disable-libquadmath \
--disable-libssp \
--disable-linker-build-id \
--disable-multilib \
--disable-nls \
--disable-plugin \
--enable-languages=c \ logs-and-others.tar.xz

--enable-sjlj-exceptions \
--enable-targets=x86 \
--enable-threads=posix \
--prefix=/home/yannick/apps/gcc-$VERSION/installed \
--program-suffix=-$VERSION \
-v \
--with-sysroot=/ \
--with-system-zlib \
Note I added `--disable-gnu-unique-object`, as I though this was the cause
of the error, but it solved nothing. The same error with and without
`--disable-gnu-unique-object`.
I'm attaching `logs-and-others.tar.xz` to this message, an archive
containing all logs, stderr/stdout listing, among others stuffs.
I will try with `--disable-sjlj-exceptions`, although I was expecting to get
Setjump/Longjump exception mechanism (for the Ada compiler).
