Hi

My 2 cents. That i386-elf GCC build has not `libgcc_eh.a' library

find /opt/ecos/gnutools/i386-elf/ -name libgcc_eh.a
<< no output >>

but the library is "used" for synth

hal/synth/arch/current/src/synth.ld:

#if (__GNUC__ >= 3)
GROUP(libtarget.a libgcc.a libsupc++.a libgcc_eh.a)
#else
GROUP(libtarget.a libgcc.a)
#endif

Can we manage the check the above with CDL?

Because 2 odd? steps to make synth tests are necessary

1) Import this option

cdl_option CYGBLD_GLOBAL_COMMAND_PREFIX {
    user_value i386-elf
};

2) Workaround for the absent libgcc_eh.a in ld GROUP

sed -i 's/ libgcc_eh.a//' install/lib/target.ld
