21.4 This patch gets 21.4 working under MacOS 10.4 (Tiger). In addition to the dll fix already posted for 21.5 it fixes a name clash between a static variable and the global 'initialized'. It seems that gcc 4.0 is fussy about such things. These changes are backward compatible to earlier versions of MacOS X. src/ChangeLog addition: 2005-07-11 Malcolm Purvis <malcolmp(a)xemacs.org&gt; * glyphs-gtk.c: Rename a local static variable because gcc 4.0 says it clashes with a global with the same name. 2005-07-11 Atanu Ghosh <atanu(a)icsi.berkeley.edu&gt; * sysdll.c (dll_open): Under MacOS X return NULL under the filename is NULL. Fixes problems finding local symbols under 10.4 (Tiger)
