[Crash-utility] [PATCH] Fix gcc-11 compiler warnings on gdb-10.2/gdb/symtab.c
Without the patch, the following gcc-11 compiler warnings are emitted
for gdb-10.2/gdb/symtab.c:
symtab.c: In function 'void gdb_get_datatype(gnu_request*)':
symtab.c:7131:31: warning: ISO C++17 does not allow 'register' storage class
specifier [-Wregister]
7131 | register struct type *type;
| ^~~~
symtab.c:7132:31: warning: ISO C++17 does not allow 'register' storage class
specifier [-Wregister]
7132 | register struct type *typedef_type;
| ^~~~~~~~~~~~
...
Usually we don't fix compiler warnings for gdb, but these are emitted
even by "make clean ; make warn", which doesn't recompile the whole
gdb, so it would be better to fix.
