["arcangelpip at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #11 from arcangelpip at hotmail dot com  2007-04-05 13:21 -------
I'm sorry to drag this back up again, but it happened again on 4.2.
Again it is with the gettext package which seems to love me so much.

Using built-in specs.
Target: i686-pc-mingw32
Configured with: ../gcc-4.2/configure --prefix=/crosstools/gccwin
--target=i686-pc-mingw32 --enable-shared --enable-threads --disable-multilib
--disable-nls --enable-languages=c,c++,ada,fortran,objc,obj-c++ --enable-c99
--enable-long-long --enable-sjlj-exceptions --enable-libada --enable-boehm-gc
Thread model: win32
gcc version 4.2.0 20070403 (prerelease)

It ICEs with the following.

I configured gettext with

../gettext-0.16.1/configure --prefix=/crosstools/gccwin
--build=i686-pc-linux-gnu --host=i686-pc-mingw32 --disable-java
--disable-native-java --with-libiconv-prefix=/crosstools/gccwin
--disable-threads --disable-openmp

If I am doing anything wrong here I'm open to suggestions.
