Is there a (reasionably easy) way to use this option only when compiling
in the .../dissectors directory ?

(I think that I've previously addressed the "unused_but_set" warnings
for many (all ?) of the other directories). (SVN 37600 & following...)

PS: I've been using

AC_WIRESHARK_GCC_CFLAGS_CHECK(-Wno-error=unused-but-set-variable)

so that "unused-but-set-variable" is reported but treated as a warning
instead of an error.
