Including time.h header causes VC 7.1 to barf ? ...

[Alfonso Morra]

Hi I'm compiling some code and need to generate some random numbers. To
save time, I decided to use the srand, rand and time functions.

My code worked (atleast built fine) until I added time.h, then the
compiler (VC7.1) barfed up this lot:

This is not the first time I have seen the compiler complain about a set
of core (i..e Microsoft supplied) headers. Does anyone know what is
going on?. Is this a bug?

In case anyone was wondering, the code am writing is a one source file
and there are no #defines so I don't think this is due to name
collisions. I will be very grateful to hear from someone who knows the
cause of this.

Hi Alfonso!

Hi I'm compiling some code and need to generate some random numbers. To
save time, I decided to use the srand, rand and time functions.

My code worked (atleast built fine) until I added time.h, then the
compiler (VC7.1) barfed up this lot:

For me the following works perfectly:

#include <stdio.h>
#include <time.h>
#include <tchar.h>

int _tmain()
{
return 0;
}
