[Paul Eggert]

branch: master
commit 28578f87b52ead4d31479fdcfba028118dfa6987
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Prefer static to extern in ebrowse
    
    * lib-src/ebrowse.c (info_where, info_cls, info_member)
    (info_position, options, yyival, yytext, yytext_end, yyout)
    (yyline, filename, is_ident, is_digit, is_white, f_append)
    (f_verbose, f_very_verbose, f_structs, f_regexps)
    (f_nested_classes, min_regexp, max_regexp, inbuffer, in)
    (inbuffer_size, string_start, class_table, member_table)
    (namespace_alias_table, global_symbols, current_namespace)
    (all_namespaces, namespace_stack, namespace_stack_size)
    (namespace_sp, tk, keyword_table, search_path)
    (search_path_tail, scope_buffer, scope_buffer_size)
    (scope_buffer_len): Now static.
    (options): Now const.
