118, 119, 124, 132, 134, and 137: Linix 2.0 (actually libc 5.3.12) changed
the way that directory manupulation was done. This was reported by many folks:
root@kirk.vossnet.de,thogard@not.abnormal.com,root@startrek.in-trier.de,
babina@pex.net,mding@hcia.com,rog@therion.lamc.utexas.edu,icculus@visi.net,
tundra@nnenews.com,sohos@enviro-eng.com,fmouse@fmp.com,c15o@zfn.uni-bremen.de,
100326.567@CompuServe.COM,JWHITFIELD@wwcc.cc.wy.us,sgarrett@technomancer.com,
sullivan@odysseus.gonzaga.pvt.k12.dc.us,root@internexus.net,mahadi@mtk.kpm.my,
logic@shell.break.com.au,bat@xdiv.lanl.gov,aaron@onr.com,crosser@average.org

The problem was that glob.c would not compline on Linux 2.X systems.

The fix was one suggested by crosser@average.org along with some work by me to
insure that Linux 1.X users would still be able to use this on their systems.
-------------------------------------------------------------------------------
