Optimisation bug on Sparc

[Ludovic Drolez]

GCC: 2.95.2 / Sparc
System: Sun SS20 on Solaris 2.5
Options: -O

Tcl 8.3.0 when compiled with the default option (-O)
has a problem with the 'glob' function, which should
return the list of files in the current directory.

example: 'glob *'
with -O: returns: {} {} {} {} {} {} {} {} {}
     => empty list = bug

with -O2: returns: index.html loca.ps mbox ...
     => list of files in the current directory = OK

To fix the compilation bug, I set the optimisation
flag to -O2 (instead of -O).
Strange bug ? Usualy when you ask for higher optimisation
you have more trouble. Here it's the contrary !
