Re: problem when making a new target

["Roger.Gough" <Roger dot Gough at ul dot ie>]

Thanks Andreas for that.

I think i have a bigger problem so. The target files that I am using work on
gcc-2.95. I have modified these files slightly so suit my criteria and I
want to use these on gcc3.2.2.

Can I comment out the #pragmas in system.h and hence use the macros which
otherwise would have been poisoned? If not how am I going to implement my
function_epilogue and function_prologue?

Thanks

The problem is with your target file.  You use the macros above,
e.g. BLOCK_PROFILER in your target files and those macros are
forbidden.  We explicitly have poisoned them so that you do not use
them ;)
