The list of builtin functions in the node "C Dialect options" seems
to be incorrect:
`-fno-builtin'
Don't recognize builtin functions that do not begin with
`__builtin_' as prefix. Currently, the functions affected include
`abort', `abs', `alloca', `cos', `exit', `fabs', `ffs', `labs',
`memcmp', `memcpy', `sin', `sqrt', `strcmp', `strcpy', and
`strlen'.
For instance, memset seems to be a builtin:
$ echo "int memset(int);" | gcc -x c - -c -o /dev/null
:1: warning: conflicting types for built-in function `memset'
