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
