Bug 151598 – dev-lang/pike-7.6.86-r1's mmx useflag is pointless

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Simon Stelling (RETIRED) 2006-10-16 08:16:57 UTC]

pike's configure always returns no for the MMX check, thus always disabling it, effectively ignoring the use flag:

configure:45222: checking for working MMX

|       try_use_mmx=mmx_ok();
|     }

|   return 0;
| }
configure:45295: result: no

I suggest you either fix the check or remove the USE flag :)
