Description Mike Frysinger 2006-07-03 21:12:12 UTC

the openat code uses stdarg functions but the func prototype isnt variable (it
doesnt end in ...) which of course causes a build failure

if current cvs head is configured with:
--enable-kernel=2.6.17

the build bombs:
x86_64-pc-linux-gnu-gcc ../sysdeps/unix/sysv/linux/openat.c -c -std=gnu99 -O2
-Wall -Winline -Wwrite-strings -fmerge-all-constants -g -Wstrict-prototypes

Created attachment 1222 [details]
Proposed patch for the openat.c

Proposed is a fix for the openat.c compilation error
with --enable-kernel=2.6.17

Comment 3 Mike Frysinger 2006-08-26 05:13:49 UTC

are you kidding me ?  if you looked at the openat.c, you'd see that it's
obviously wrong

so i'll dupe it for you to the correct bug (which you fixed instead of simply
marking a dupe of *this* bug)
