On a 150 MB FAT16 ramdisk I installed the following zips:

bnu226br3
gcc610b
gpp610b
djdev205

and wrote the following BAT file:

==================
@echo off
set /a i=1

:loop
echo iteration %i%
gpp test.cpp -o test.exe
if errorlevel 1 goto fail
set /a i=i+1
goto loop

:fail
echo failed at iteration %i%

==================


test.cpp is a simple hello world:

==================
#include <iostream>
using namespace std;

int main()
{
    cout << "Hello, world!" << endl;
    return 0;
}
==================

On the first trial, it failed at 7th iteration with bogus compilation error 
inside iostreams.

Consecutive trials seem to work longer and longer: 8, 14, 36, 84.

So I restarted the machine. Again, failure on 5th attempt.
That's nowhere near "several hundreds" you are getting.
