changes made to gmon-sol2.c not reflected after recompiling gcc

["Hari K. Pyla" <harip@xxxxxx>]

Hi,
      I edited the following functions in gmon-sol2.c in 
gcc-4.1.1/gcc/config/i386 directory
(i) monstartup()
(ii) _mcleanup()
(iii) internal_mcount()
(iv) moncontrol()
basically added some fprintf()'s,  changed the filename "gmon.out" to 
"newgmon.out" in create() and  recompiled gcc with the following options
./configure
make
make install

The changes do seem to be reflected in the new build of gcc. Is there 
anything that I am missing. I appreciate you taking time to answer this.
Thanks in advance.

Regards,
