Errors in eldap.c?

I'm building XEmacs 21.4.3 from source (xemacs-21.4.3.tar.gz) on a Mandrake 7.2-ish system and have run into the following compilation errors in eldap.c. A quick search of google and xemacs.org didn't turn up anything relevant. Has anybody else hit similar problems? gcc -c -g -O3 -Wall -Wno-switch -Winline -Wmissing-prototypes -Wshadow -Wsign-compare -Demacs -I. -DHAVE_CONFIG_H -I/usr/X11R6/include eldap.c eldap.c: In function `Fldap_open': eldap.c:322: dereferencing pointer to incomplete type eldap.c:323: dereferencing pointer to incomplete type eldap.c:324: dereferencing pointer to incomplete type eldap.c:328: dereferencing pointer to incomplete type eldap.c:331: dereferencing pointer to incomplete type eldap.c: In function `Fldap_search_basic': eldap.c:568: dereferencing pointer to incomplete type eldap.c:67: warning: inlining failed in call to `signal_ldap_error' eldap.c:568: warning: called from here make[1]: *** [eldap.o] Error 1 make[1]: Leaving directory `/usr/local/src/xemacs-21.4.3/src' -Barry
