I keep the older versions of GCC around for this case: [hjl@gnu-cfl-3 usr]$ ls -d /usr/gcc* /usr/gcc-10.2.1-32bit /usr/gcc-12.3.1-32bit /usr/gcc-14.0.1-x32 /usr/gcc-10.2.1-mx32 /usr/gcc-12.3.1-mx32 /usr/gcc-6.4.1-x32 /usr/gcc-10.2.1-x32 /usr/gcc-12.3.1-x32 /usr/gcc-7.4.1-x32 /usr/gcc-11.2.1-32bit /usr/gcc-13.2.1-32bit /usr/gcc-8.4.1-x32 /usr/gcc-11.2.1-mx32 /usr/gcc-13.2.1-mx32 /usr/gcc-9.3.1-x32 /usr/gcc-11.2.1-x32 /usr/gcc-13.2.1-x32 [hjl@gnu-cfl-3 usr]$ -- H.J.
