of course ... your subject says "GCC 4.2.x" after all and using anything other 
than 4.2.2 would be silly considering the # of crap bugs in gcc-4.2.x so far

only "extern inline" is changing meaning, but glibc forces -fgnu89-inline onto 
the build system, so that doesnt matter

nowadays, you should not have symlinks in /usr/include for your kernel 
headers ... are you saying you're 
symlinks /usr/include/... -> /usr/src/linux/include/... ?  also, you never 
patch configure, you patch configure.in and regenerating configure is 
implied.
