     1.6  --------------------------------
     1.7 +Symptoms:
     1.8 +  On x86_64 hosts with 32bit userspace the GMP build fails with:
     1.9 +    configure: error: Oops, mp_limb_t is 32 bits, but the assembler code
    1.10 +    in this configuration expects 64 bits.
    1.11 +    You appear to have set $CFLAGS, perhaps you also need to tell GMP the
    1.12 +    intended ABI, see "ABI and ISA" in the manual.
    1.13 +
    1.14 +Explanations:
    1.15 +  "uname -m" detects x86_64 but the build host is really x86.
    1.16 +
    1.17 +Status:
    1.18 +  CURRENT
    1.19 +
    1.20 +Fix:
    1.21 +  None so far. See above issue.
    1.22 +
    1.23 +Workaround:
    1.24 +  use "setarch i686 ct-ng build"
