Description Jeremy Warren 2003-02-10 14:37:47 UTC

This package will fail to compile with the following CFLAGS: 
-march=pentium4 -O2 -pipe -fPIC 
 
It appears to be directly related to the -march=pentium4 flag.		 

Reproducible: Always
Steps to Reproduce:
1.  Change CFLAGS to -march=pentium4 
2.  Compile and watch it bomb. 
3.  Lather, rinse, repeat as necessary. 
Actual Results:  
After a couple of searches on the Gentoo forums, there was some mention about 
"aggressive" CFLAGS.  I changed to -mcpu=i686, and it works just fine. 

Expected Results:  
Should filter out "pentium4" cflags and replace them with i686. 

I have no idea if this is similar for Athlons.
