This is as much as the documentation says about it: "If the output is more
than one line long, each line will be expanded to a new parameter. Setting
IFS to the empty string will disable line splitting."
I'm guessing this fits in with the "law of orthogonality" (
http://fishshell.com/docs/current/design.html)
One way to get the result you want without eval would be
gcc -o snmpdemoapp snmpdemoapp.o (net-snmp-config --libs | tr -s
'[:space:]' '\n')
That way, each word comes out on a separate line
