compile error in CVS HEAD

I see the following error with the current CVS code:

make[3]: Entering directory `/home/nconway/pgsql/src/backend/commands'
[ ... ]
gcc -O2 -DLINUX_PROFILE -g -pg -Wall -Wmissing-prototypes -Wmissing-declarations

-I../../../src/include  -c -o copy.o copy.c
 
copy.c: In function `DoCopy':
copy.c:425: `errno' undeclared (first use in this function)
copy.c:425: (Each undeclared identifier is reported only once
copy.c:425: for each function it appears in.)
make[3]: *** [copy.o] Error 1

Cheers,

Neil
