Subject: libcdecl: Don't propagate specifier lists more than once.
X-Git-Tag: v1.3~114
X-Git-Url: https://git.draconx.ca/gitweb/cdecl99.git/commitdiff_plain/7faacc8b3fbc810ec92faa0c38af5270e3bd1b4e

libcdecl: Don't propagate specifier lists more than once.

The very first thing the library does with the parse tree is normalize
the top-level specifiers, and then propagate the resulting list across
all top-level declarators.

So it is completely redundant for the parser itself to propagate the
un-normalized specifier list.
