gcc-3.3.2-newlib-1.13.0 complier error


Hi, everyone!

I have compliered gcc-3.3.2-glibc-2.3.2 on cygwin for mpc860 successfully by crosstool-0.38. Now I want to build gcc-3.3.2-newlib-1.13.0 crosstool, and then met errors:

I find the maillist and find some info which say that I need a glibc, but actually I just want to build gcc with newlib.


There is a patch for gcc-3.4.0, and I think it will work OK, but I relly need some suggestions about this.
