+gcc 3.2.1 is known to work okay with Perl 5.8.0. However, when
+optimizing the toke.c gcc likes to have a lot of memory, 256 megabytes
+seems to be enough. The default setting of the process data section
+in Tru64 should be one gigabyte, but some sites/setups might have
+lowered that. The configuration process of Perl checks for too low
+process limits, and lowers the optimization for the toke.c if
+necessary, and also gives advice on how to raise the process limits.

+Also, Configure might abort with
+
+ Build a threading Perl? [n]
+ Configure[2437]: Syntax error at line 1 : `config.sh' is not expected.
+
+This indicates that Configure is being run with a broken Korn shell
+(even though you think you are using a Bourne shell by using
+"sh Configure" or "./Configure"). The Korn shell bug has been reported
+to Compaq as of February 1999 but in the meanwhile, the reason ksh is
+being used is that you have the environment variable BIN_SH set to
+'xpg4'. This causes /bin/sh to delegate its duties to /bin/posix/sh
+(a ksh). Unset the environment variable and rerun Configure.
