 I have (I remembered what you told me), and I also changed setting in
 compilers-1.0.tcl to:

 {{{
 # GCC version providing the primary runtime
 # Note settings here *must* match those in the lang/libgcc port.
 if { ${os.major} < 11 } {
     set gcc_main_version 10
 } else {
     set gcc_main_version 11
 }
 }}}

 Then I uninstalled `libgcc` and installed again. This however did not
 help.
