where the min() macro is defined

I've had some minor problems reading email this weekend, but I'm
pretty certain Mark Post asked about where I'd found the min()
definitions -

sys/src/co/sap/saptypeb.h:  #define min(a,b)       (((a) <= (b)) ? (a) : (b))
sys/src/en/gen00.h:#define min(a,b)        ( ( (a) <= (b) ) ? (a) : (b) )
sys/src/pa/hpa106cslzc.h:#define min(a,b) ((a) < (b) ? (a) : (b))
sys/src/pa/vpa00wic:#define min(a,b)            (((a) < (b)) ? (a) : (b))
sys/src/sp/vsp00c:#define min(a,b)        ( ( (a) <= (b) ) ? (a) : (b) )
sys/src/wd/fcgimisc.h:#define min(a,b) ((a) < (b) ? (a) : (b))
sys/src/sap/saptypeb.h:  #define min(a,b)       (((a) <= (b)) ? (a) : (b))
sys/src/SAPDB/TclTools/sdbodbc/sdbodbc.h:#define min(a, b) ((a) < (b) ? (a) : 
(b))

I tried adding a "#undef min" in 
sys/src/SAPDB/LVCSimulator/LVCSim_liveCacheSink.cpp
and then compile again - problem with std::min disappeared. So it's now only
a matter of finding who incorrectly defines min(). 
Or maybe just undef'ing it ?
