description:
lint: fix lint warning on platforms where size_t == unsigned int

lex.c(1451): warning: argument #1 is converted from 'int' to
    'unsigned int' due to prototype [259]

A more thorough fix would be to change the type of block_level from int
to size_t, to match mem_block_level, but that change would generate
further signedness warnings because the type of sym_t.s_block_level
would have to be changed from int to size_t as well, but some symbols
have s_block_level == -1, so that's a larger and more error-prone
change.  Leave that for later.

Whether message 259 makes sense at all in C99 mode is an entirely
different question that needs to be answered separately.

No functional change.
