compile error, please help

[Duane Cox]

I want to use monit to monitor my BIND daemon.
When compiling monit on the server, I get this error.

gcc -c -g -O2 -Wall -D
_REENTRANT -DLINUX  -I. -I./device -I./http -I./process -I./protocols
process/sysdep_LINUX.c -o process/sysdep_LINUX.o
process/sysdep_LINUX.c: In function `init_process_info_sysdep':
process/sysdep_LINUX.c:131: error: `errno' undeclared (first use in this
function)
process/sysdep_LINUX.c:131: error: (Each undeclared identifier is reported
only once
process/sysdep_LINUX.c:131: error: for each function it appears in.)
make: *** [process/sysdep_LINUX.o] Error 1
