compilation problem on Snow leopard Mac osx in SortedDataWriter.cpp

Hello,

Just tried to compile SNAP with latest code but got following error:

++ -O3 -Wno-format -MMD -ISNAPLib -msse   -c -o SNAPLib/SortedDataWriter.o SNAPLib/SortedDataWriter.cpp

make: *** [SNAPLib/SortedDataWriter.o] Error 1

Is this related to the previous problem that I had https://github.com/amplab/snap/issues/40#issuecomment-99205239?

Thank you

I changed SNAPLib/SortedDataWriter.cpp line 338 from ...

min(1UL << 23, max(1UL << 17, bufferSpace / blocks.size())));

... to ...

min(1UL << 23, max<long unsigned>(1UL << 17, bufferSpace / blocks.size())));

and it compiled.
