LWTools: lwasm/output.c annotate

annotate lwasm/output.c @ 359:f318407d2469

Fix some signedness mismatches Use size_t instead of int for stuff that's going to be compared with the strlen() return value. While not technically wrong to use int, it does seem to attract warnings from some compilers. Technically, since it's also the return value from strtol(), there should be one variable that is long and another that is size_t but that's just getting crazy. Thanks to Erik G <erik@6809.org> for pointing these ones out.
