Tom; IT WORKED! This is what I did:
env | grep CFLAGS and that produced all those flags as you predicted (-O9 -funroll-loops -ffast-math -malign-double -mcpu=pentiumpro -march=pentiumpro) unset CFLAGS make clean ./configure --enable-odbc make make install a subsequent pg_dump of the staging system's database produced NO ":60" substrings in any time stamps! Thanks much for your help! Martin p.s. interesting to note -- my dev box is actually the same distro (slackware 8.1) but running in a vmware window. there was no such CFLAGS env variable set and pg_dumps on the dev box are ok. the distro install must set the CFLAGS based on hardware (the laptop is a Compaq PIII/700, and the staging box is a P4/1.7G on an intel chipset board). Anyway, really happy this worked -- thanks again. Let me know if there's anything I can do. > "Martin Crundall" <[EMAIL PROTECTED]> writes: >> Not sure how to tell.
