[CentOS] question after updating to 6.4

My video driver for AMD HD 4200 did not work after upgrading. I tried to fix it with 13.1 legacy drivers but that did not work I then just grapped a AMD HD 5200 video card and put on AMD 13.1 "regular" and that worked.

however,

After updating x86_64 to 6.4 and when I compile my project I get this message

make: *** No rule to make target `/usr/lib/gcc/x86_64-redhat-linux/4.4.6/include/stddef.h',

I have done a "make clean" and the message persists.

there is no directory /usr/lib/gcc/x86_64-redhat-linux/4.4.6 - there is a 4.4.7 which matches the "gcc --version"

Where is this message coming from and how can I remove it. Thanks,

Jerry
