The reason why I say it's ``more complicated than necessary'' is that
in reality, this utility is not speed-critical, so there was no
particular reason to use gperf(1) to generate an optimized search
structure -- a simple array of variable descriptors (as in
{Net,Open}BSD) would have done. But, I had already done the work (a
couple hours' worth, mostly involved in deciphering SUSv2) so I
figured I might as well check mine in. Unlike J.T. Conklin's
implementation, mine does not rely on any compile-time constants at
all -- all of the values are determined dynamically using confstr(),
pathconf(), or sysconf(). (This may mean I missed some, if there are
any which exist *only* as constants.)
