Aside from the fact that this is incorrect for cross builds, T_ADAFLAGS appears to be used only when compiling ada files in GCC. I looked at the segmentation fault that I previously reported in this thread. It occurs in process_decls in trans.c on an index instruction. Thus, "-mdisable-indexing" may have to be used in compiling the C code as well. I need to investigate further to determine why there is a problem with the base register in C code. Dave -- J.
