Then may I ask why are forcing -Werror on the face of those poor
innocent users?

These are the flags I use when compiling any program, without
testing I'm sure there are quite a bunch of warnings these reveal
in GnuCash:


-O3 -Wall -Wextra -Wfloat-equal -Wredundant-decls
-Wmissing-noreturn -Wno-shadow -Wendif-labels -Wlarger-than-65500
-Wpointer-arith -Wno-cast-qual -Wcast-align -Wwrite-strings
-Winline -Wformat=2 -Winit-self -Wno-switch-default
-Wno-switch-enum -Wno-unused-parameter -Wundef -Wno-error
-Wmissing-declarations -Wmissing-prototypes -Wstrict-prototypes
-Wold-style-definition -Wdeclaration-after-statement
-Wbad-function-cast


(and yes, packages like GnuCash has forced me to add that
-Wno-error there, cause when I'm compiling something, especially
one that I don't have commit access/permission to, I really want
to compile it, not be interrupted and forced to fix the
warnings.)

No, there are a few others too.

I'm sure this list has had enough discussion on -Werror before.
No need to continue it here.  If you are interested, I'm going to
continue my rants on my blog tonight (http://mces.blogspot.com/)
