Problem building libada

[JonY]

Hi,

I am trying to build gcc svn trunk, xgcc seems to go on forever trying 
to compile g-catiio.adb with the default -O2, gnat1 consumes 90% of the 
CPU time, manually compiling it with -O0 works.

What options should I pass to the top level configure to disable 
optimizations for ada? For example, "../gcc/configure LDFLAGS=-Wl,-S" 
for stripped executables.

Thanks.
