hello, I am interested to build gcc with a slightly modified gcc/gmon.c file(instead of writing to the results into gmon.out I write the results into gmon.out.PID where PID is the process id of the current process). When I compile the sources(./configure --prefix=/home/gabrielt/gnu ; make; make install or ./configure; make bootstrap; make install) the gmon.c is never compiled. Can anybody point me to some documentation about how I can compile and include a modified gmon.c Thanks, GAbi
