What doesn't work with it?  It seems to work fine in a test here (with
both 2.59 and current).  Maybe there is some other code around it which
causes the problem (e.g., PATH_NET_SNMP_CONFIG is also a m4 defined
name, or these two lines are part of an underquoted expansion)?

FWIW, the only change this quoting gets me is inside of a comment.
Looking at the diff of the configure scripts may hint you at what
is different for you.
