autoconf-2.52 not a speed demon ?? --

[Paul Townsend]

Ladies and/or Gents,

I know this mail address is for suggestions but I'm not sure the bug mail
address is appropriate either.  I just upgraded from autoconf-2.13 to
autoconf-2.52 and either I have done something incredibly stupid (an
always present possibility) or the 2.52 version does its thing extremely
slowly.  Below are the 2.13 and 2.52 runs of `autoconf' using a modified
"configure.in" from the OpenSSH distribution.  According to `time', the
2.52 version takes about 15-20 times as long to execute as the 2.13
version.  Have I screwed up somewhere?  Another indication of slowness
is the 3 hours the 2.52 version takes to execute its own "gmake check".
Most of the time seems to spent in `gm4' followed by `nawk'.
