Further unwinding of the problem is that on my amd64 (Mageia 3) system,
size_t winds up being resolved as an 'unsigned long int' in the gcc 4.7.2
headers (/path/to/gcc/4.7.2/include/stddef.h). The line in question is:
for ( i = 0; i < _yybytes_len; ++i )
where 'i' is an int, and _yybytes_len is size_t. Since timep.c is generated
by flex, so changing the _yy* variables isn't an easy out. We could add
#define YY_TYPEDEF_YY_SIZE_T
typedef long int yy_size_t
size_t is required to be an unsigned type, so this would just mask the
problem.
Ok - then making the local variable 'i' unsigned would work, but that would
get into the middle of the flex generation.
Ultimately we could also turn off the gcc warning, but that too would
defeat the purpose.
What version of flex are you using? And what's your OS version/patch-level?
[jerry@unix Downloads]$ rpm -qa | grep flex
flex-2.5.37-2.mga3
[jerry@unix Downloads]$ uname -a
