gcc-4.4 -Wconversion produces warnings in sysdeps/i386/bits/select.h and
sysdeps/x86_64/bits/select.h header files.
For example, on i386:
$ printf '%s\n%s\n' '#include <sys/select.h>' 'int f(fd_set *s, int d) {return
FD_ISSET(d, s);}' |gcc -Wconversion -c -xc -
<stdin>: In function f:
<stdin>:2: warning: conversion to unsigned int from int may change the sign
of the result
<stdin>:2: warning: conversion to unsigned int from int may change the sign
of the result
$ printf '%s\n%s\n' '#include <sys/select.h>' 'int f(fd_set *s, unsigned int d)
{return FD_ISSET(d, s);}' |gcc -Wconversion -c -xc -
<stdin>: In function f:
<stdin>:2: warning: conversion to unsigned int from int may change the sign
of the result
That is, FD_ISSET() produces warnings regardless of integer type.
