They show up if one uses -Wconversion (on my 64 bit Linux platform) but they are swaped by other warnings so it is not enabled by default. For example this file: > subversion/libsvn_subr/cache-membuffer.c: In function > 'svn_cache__membuffer_cache_create': > subversion/libsvn_subr/cache-membuffer.c:1078: warning: implicit conversion > shortens 64-bit value into a 32-bit value has these warnings with -Wconversion -Wno-sign-conversion on 64 bit Linux: ../src/subversion/libsvn_subr/cache-membuffer.c: In function ‘is_group_initialized’: ../src/subversion/libsvn_subr/cache-membuffer.c:705: warning: conversion to ‘unsigned char’ from ‘int’ may alter its value ../src/subversion/libsvn_subr/cache-membuffer.c: In function ‘initialize_group’: ../src/subversion/libsvn_subr/cache-membuffer.c:729: warning: conversion to ‘unsigned char’ from ‘int’ may alter its value ../src/subversion/libsvn_subr/cache-membuffer.c: In function ‘svn_cache__membuffer_cache_create’: ../src/subversion/libsvn_subr/cache-membuffer.c:1078: warning: conversion to ‘apr_uint32_t’ from ‘long unsigned int’ may alter its value -- uberSVN: Apache Subversion Made Easy http://www.uberSVN.com
