I am porting GCC for a 32 bit RISC. I have not defined macros for debug
information support yet.
I am using the following options in my build.
--without-headers --disable-shared --disable-libssp --disable-libgomp
--disable-fixed-point --enable-languages=c --disable-threads
--enable-sjlj-exceptions=no
I wanted to avoid building exception handling routines, so I used
--enable-sjlj-exceptions=no. I am not sure if this is correct.
And while building libgcc, I get the following error.

In file included from build/gencondmd.c:43:

../../gccport/gcc-4.3.0/gcc/gcc/except.h:163:6: error: #error
"{DWARF2,TARGET}_UNWIND_INFO required"

We need to define these macros mandatorily? Also how should I disable
building the exception handling routines?
Please assist.
