sudo compiling error

[Mubaraki, Altaf (DCS)]

Hi all:

I am trying to compile sudo ver 1.6.3p5 on a solaris 2.6 box. When I run make it aborts while compiling interfaces.c.  Here is the error I get:

gcc -c -I. -I.  -D__EXTENSIONS__ -g -O2 -D_PATH_SUDOERS=\"/etc/sudoers\" -D_PATH_SUDOERS_TMP=\"/etc/sudoers.tmp\" -DSUDOERS_UID=0 -DSUDOERS_GID=0 -DSUDOERS_MODE=0440  interfaces.c

Last year, when I first installed sudo (same version) on this machine, the installation went smoothly. Unfortunately, I had to remove it later on as I didn't have an OK from my manager. Incidentally, I get the 'warning: NBBY redefined' while compiling all the objects in SRCS.

Would be obliged to one any who may shed light as to what am I missing...

Thanks,
