Short summary: there's plenty of implicit type and sign conversions around.
If you recall that side project I was doing ever now and again to
improve the compiler warnings situation. -Wshadow got done but -Wcasting
and -Wconversion and a few others are still very much TODO.
The situation as it stands for conversion is that *certain* very
specific dangerous conversions are highlighted as errors by the
compilers I refer to in commit messages as "strict" (clang, ICC and Sun
Studio mainly). However the vast majority of conversions are considered
safe by compilers and they all only produce warnings which we are *not
yet* catching with Squid compile flags.
If you build with "-Wconversion -Wsign-conversion
-Wtraditional-conversion" on a recent GCC you will see a list of what
needs investigating still. (sorry have not yet made bugs to track them).
