[zile-devel] 2.2.1: excessive compiler warning flags

[Christian Weisgerber]

I just looked at building zile 2.2.1 on amd64 and I'm getting excessive
compiler warnings, e.g.:

--------------->

<---------------

Most of these are caused by int constants being passed as arguments
for size_t parameters (size_t expands to unsigned long on LP64
architectures, i.e., uint64_t), which is totally harmless.  Asking
gcc to complain about this with this string of -W options is excessive
and only obscures real problems.
