I got
[EMAIL PROTECTED] applied]$ /usr/gcc-4.3/bin/gcc --version
gcc (GCC) 4.3.0 20070612 (experimental) [trunk revision 125661]
...
[EMAIL PROTECTED] result]$ /usr/gcc-4.2/bin/gcc --version
gcc (GCC) 4.2.1 20070619 (prerelease) [gcc-4_2-branch revision 125849]
...
I am enclosing 2 patches I have been using for more than a year.
