gcc -Wall, via "make gcc-wall" and "make gcc-wall-new"
Annoyingly, I ran make gcc-wall on Ubuntu 12.04 (gcc 4.6, glibc 2.15) and got
this splat:
/usr/include/x86_64-linux-gnu/sys/stat.h:456: multiple definition of `stat'
../lib/libquota.a(quotaio_v2.o):/usr/include/x86_64-linux-gnu/sys/stat.h:456: first defined here
Not sure how to fix this, other than changing WFLAGS to start with -std=gnu99.
gcc 4.8/glibc 2.19 on Ubuntu 14 are no better.
Hmm, I'm using Debian testing, with gcc 4.8 and eglibc 2.18, and it's
working fine. I'm curious, are people noticing problems with gcc-wall
on Fedora?
I got the similar error as Darrick on Fedora 19 x86_64:
$ make gcc-wall
