Re: Multilib support

[Tzu-Chien Chiu]

Hello, Ralf.

I found gcc and newlib don't use AM_ENABLE_MULTILIB, instead
TARGET_SUBDIR is set.

ChangeLog (gcc 3.4.4):

Thu Jun 19 14:16:42 1997  Brendan Kehoe  <address@hidden>

       * configure.in: Don't set ENABLE_MULTILIB, so we'll be passing
       --enable-multilib down to subdirs; setting TARGET_SUBDIR was enough.


I think neither how gcc nor newlib does things is not what I'm looking
for. I need to build *both* the native and the cross-compiled library
at the same time (one-time configure script and make), rather than
*either one* of them.
