# hints/solaris_2.sh
# Contributions by (in alphabetical order) Alan Burlison, Andy Dougherty,
# Dean Roehrich, Jarkko Hietaniemi, Lupe Christoph, Richard Soderberg and
# many others.
#
# See README.solaris for additional information.
#
# For consistency with gcc, we do not adopt Sun Marketing's
# removal of the '2.' prefix from the Solaris version number.
# (Configure tries to detect an old fixincludes and needs
# this information.)
# If perl fails tests that involve dynamic loading of extensions, and
# you are using gcc, be sure that you are NOT using GNU as and ld. One
# way to do that is to invoke Configure with
#
# sh Configure -Dcc='gcc -B/usr/ccs/bin/'
#
# (Note that the trailing slash is *required*.)
# gcc will occasionally emit warnings about "unused prefix", but
# these ought to be harmless. See below for more details.
# Solaris has secure SUID scripts

# Be paranoid about nm failing to find symbols
mistrustnm=${mistrustnm:-run}
# Several people reported problems with perl's malloc, especially
# when use64bitall is defined or when using gcc.
