Bugzilla Bug 190091

The 6200ch channel changer program needs -std=gnu99 to compile.  If the C
standard is not set, compilation fails with LLONG_MAX and LLONG_MIN not
defined.  All mythtv-0.21_preXXXXX currently in portage fail to build with
ieee1394 because of this.  -std=gnu99 needs to be added after the ${CFLAGS} on
line 193 of mythtv-0.21_pre14278.ebuild.

Reproducible: Always

Steps to Reproduce:
1. Set ieee1394 use flag.
2. emerge =media-tv/mythtv-0.21_pre14278

post your emerge --info out of curiosity.

Odd. -std=gnu99 is the default in gcc. I don't see anything you've tweaked that
would change that. I'll add that flag however.

The default is -std=gnu89 in both gcc-4.1.2 and gcc-4.2.1.

Fixed in 0.21_p14327
