testcase re: -Wmissing-field-initializers and designated initializers
According to gcc(1):
-Wmissing-field-initializers
Warn if a structure's initializer has some fields missing. ... This
option does not warn about designated initializers ....
This I find normally to be true. Attached is a test case that produces the
following warning on GCC 4.2.1, 4.4.4., and 4.5.2:
$ gcc -save-temps -Wmissing-field-initializers -c test3.c
test3.c:14: warning: missing initializer
test3.c:14: warning: (near initialization for ‘(anonymous)[0].b’)
If the `b' field is initialized either before or after the `a' field, the
warning disappears, but this should not be necessary, according to the
documentation.
