manywarnings: improve port to GCC 10.1 * build-aux/gcc-warning.spec: Also list warnings that are default or are enabled by already-given flags. This lets us speed up checking for attributes, and makes the generated compilation commands shorter. Add -Wanalyzer-too-complex (too much noise). * m4/manywarnings.m4 (gl_MANYWARN_COMPLEMENT) (gl_MANYWARN_ALL_GCC): Use gl_AS_VAR_APPEND to append to shell variables that may have long values. (gl_MANYWARN_ALL_GCC): Omit flags that are default or are consequences of other flags, to speed up checking and shorten commands.
