Not yet compiled with a 64bit time_t.
>Description:
If I optimise for my ultrasparc 2 processor by using the
compile option:
-mcpu=ultrasparc
I get the following build failure:
/usr/include/sys/user.h:105:2: #error "Unknown architecture"
>How-To-Repeat:
Simple code to demonstrate this:
#include <stdio.h>
#include <sys/param.h>
#include <sys/user.h>
int main() {
printf("Hello World\n");
return 0;
}
Testing compiling normally and with -mcpu:
gcc -Wall -o hello hello.c
gcc -Wall -mcpu=ultrasparc -o hello2 hello.c
In file included from hello.c:3:
/usr/include/sys/user.h:105:2: #error "Unknown architecture"
The first compile worked fine, and the second failed.
>Fix:
Unsure. There's some tests in user.h which are all failing.
Maybe another case needs to be added?
