Here is another very similar problem with Borland CRT.
(was catched due to failing test in Perl and then workaround was made to
surpass this)
#include <errno.h>
#define TEST(a) \
uv = strtoul(a, (char**)0, 10); \
printf("str=%s uv=%u errno=%d\n",a,uv,errno);
void main()
{
unsigned int uv;
TEST("4294967295");
TEST("4294967296");
TEST("4294967297");
TEST("42949672950");
TEST("42949672960");
TEST("42949672970");
TEST("42949673970");
TEST("4294967299");
TEST("4294967300");
TEST("9999999999");
}
This program outputs
str=4294967295 uv=4294967295 errno=0
str=4294967296 uv=0 errno=0
str=4294967297 uv=1 errno=0
str=42949672950 uv=4294967295 errno=34
str=42949672960 uv=0 errno=0
str=42949672970 uv=10 errno=0
str=42949673970 uv=4294967295 errno=34
str=4294967299 uv=3 errno=0
str=4294967300 uv=4294967295 errno=34
str=9999999999 uv=4294967295 errno=34
