+Wargs
+Warg1[,arg2,..argn]
The +Wargs option selectively suppresses any specified warning messages.
Arguments arg1 through argn are valid compiler warning message numbers.
Example:
aCC +W600 app.C
+Wcontext_limit
+Wcontext_limit=num
The +Wcontext_limi option limits the number of instantiation contexts output by the
compiler for diagnostics involving template instantiations. At most num outermost contexts
and num innermost contexts are shown. If there are more than 2*num relevant contexts,
the additional contexts are omitted.
Omitted contexts are replaced by a single line separating the outermost num contexts
from the innermost num contexts, and indicating the number of contexts omitted. The
default value for num is 5. A value of 0 removes the limit.
+We
+We
The +We option interprets all warning and future error messages as errors.
Alternatively you can also use +We[arg1,...argn] option, where arg is a valid
compiler warning message number. Use of arg is optional.
+Weargs
+Wearg1[,arg2,..,argn]
The +Weargs option selectively interprets any specified warning or future error messages
as errors. arg1 through argn are valid compiler warning message numbers.
Example:
aCC +We 600,829 app.C
+Wv
+Wv[d1,d2,..,dn]
The +Wv option displays the description for diagnostic message numbers d1 through dn.
Specifying this option causes the compiler to emit the descriptive text for the specified
dianostics to stderr. This option must not be used with any other compiler options.
If the description for a diagnostic is not available, the compiler emits only the diagnostic
with a note that the description is not available.
