The right way to have a compiler with -DGATHER_STATISTICS

[Andrew Pinski]

What is the right way to compile gcc with -DGATHER_STATISTICS which 
enables gathering of some more statistics?
On powerpc-apple-darwin6.6 I tried `make CFLAGS='-O2 -g 
-DGATHER_STATISTICS' ' but every time I tried I get an error
when libstdc++ is building the PCH for the testsuite.
I also tried make BOOT_CFLAGS='-O2 -g -DGATHER_STATISTICS' bootstrap 
and that caused the same error.


Thanks,
Andrew Pinski
