Not in my experience.  Unfortunately there's no single right answer to
your question.

What I do (when I have the time) is to build with both GCC and with a
non-GCC compiler; I use Sun's.

-Wall implies -Wimplicit-int and -Wformat-security these days, no?

I'd also add look into these:

   -Wno-sign-compare
   -Wno-format-zero-length

   -Wbad-function-cast
   -Wendif-labels
   -Wmissing-declarations
   -Wmissing-format-attribute
   -Wmissing-noreturn
   -Wmissing-prototypes
   -Wnested-externs
   -Wpointer-arith

If you're feeling really pedantic, you might add these:

   -pedantic -Wno-long-long
   -Wcast-qual
   -Wcast-align
   -Winline
   -Wredundant-decls
   -Wstrict-prototypes
   -Wwrite-strings
