The problem isn't that...
for (int x = 0; x < MAX; x++)
...is a problem for the Linux gcc compiler (it's perfectly fine by itself).
The problem is that in ANSI C++, the variable only has scope within the
"for" loop. The Microsoft C++ compiler let's you do this...
for (int x = 0; x < MAX; x++)
{
// stuff here
}
if (x == MAX) // did the loop complete?
// stuff here
...in ANSI C++ the 'x' within the "for" loop does not exist outside of the
loop and thus, in the "if" statement below it, 'x' is an undeclared variable
(as it should be).
The Microsoft C++ compiler just has not kept updated to adhere to the latest
ANSI standards, thus making the porting of code from Windows to Linux a
little bit more troublesome.
