Using built-in specs.

Thread model: posix
gcc version 4.0.1 (Apple Inc. build 5493)
a lot of:
/usr/include/c++/4.0.0/tr1/functional_iterate.h:912: error: cannot use typeid
with -fno-rtti
/src/gcc-4.7.0/gcc/go/gofrontend/string-dump.h: At global scope:
gcc/configure.ac:
# Disable exceptions and RTTI if building with g++
ACX_PROG_CC_WARNING_OPTS(
m4_quote(m4_do([-fno-exceptions -fno-rtti])), [noexception_flags])
Maybe best to just leave the default flags? Maybe just remove this snippet?
Or maybe this is
- meant for otherwise C code? Slightly optimize it??
- meant to reduce memory/disk use and let things work that otherwise fail?
i.e. on older hosts and/or with older g++?
Yeah yeah, I'll try without -disable-bootstrap.
If that fails though, I'll try removing those lines from configure/configure.ac.
Thank you,
