lowered that. The configuration process of Perl checks for too low

process limits, and lowers the optimization for the toke.c if
108

necessary, and also gives advice on how to raise the process limits.</p>

115
(even though you think you are using a Bourne shell by using

"sh Configure" or "./Configure"). The Korn shell bug has been reported
117
to Compaq as of February 1999 but in the meanwhile, the reason ksh is
118
being used is that you have the environment variable BIN_SH set to
119
'xpg4'. This causes /bin/sh to delegate its duties to /bin/posix/sh
120
(a ksh). Unset the environment variable and rerun Configure.</p>

<p>In Tru64 V5 (at least V5.1A, V5.1B) you cannot build threaded Perl with gcc
