speaking of rint(), I just got this on Linux on a clean get from CVS:
gcc -O2 -Wall -Wmissing-prototypes -Wmissing-declarations -fpic -I../../../.
./src/interfaces/ecpg/include -I../../../../src/include/utils -I../../../../
src/include -c -o dt_common.o dt_common.c
dt_common.c: In function `dt2time':
dt_common.c:1271: warning: implicit declaration of function `rint'
which I guess is kinda undesirable...
