            Bug ID: 67589
           Summary: go-main: int main() while return NULL
           Product: gcc
           Version: 5.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go

  Target Milestone: ---

in libgo/runtime/go-main.c,

the main method is defined 

int main, while return NULL.

NULL in ppc64el is defined (void *)0, thus fails to build when cross build for
native.

While it doesn't fail when build with cross build and native build.

I use the same version of cross toolchain to cross build a native gcc.
Both of them are gcc 5.2.1-17 in Debian.
