# cc -n32 update info from Krishna Sethuraman, krishna@sgi.com.
# additional update from Scott Henry, scotth@sgi.com
# Futzed with by John Stoffel <jfs@fluent.com> on 4/24/1997
# - assumes 'cc -n32' by default
# - tries to check for various compiler versions and do the right
# thing when it can
# - warnings turned off (-n32 messages):
# 1116 - non-void function should return a value
# 1048 - cast between pointer-to-object and pointer-to-function
# 1042 - operand types are incompatible
# Tweaked by Chip Salzenberg <chip@perl.com> on 5/13/97
# - don't assume 'cc -n32' if the n32 libm.so is missing
# Use sh Configure -Dcc='cc -n32' to try compiling with -n32.
# or -Dcc='cc -n32 -mips3' (or -mips4) to force (non)portability
# Don't bother with -n32 unless you have the 7.1 or later compilers.
# But there's no quick and light-weight way to check in 6.2.
# Let's assume we want to use 'cc -n32' by default, unless the
# necessary libm is missing (which has happened at least twice)

# I have conflicting reports about the sun, crypt, bsd, and PW
# libraries on Irix 6.2.
#
# One user rerports:
# Don't need sun crypt bsd PW under 6.2. You *may* need to link
# with these if you want to run perl built under 6.2 on a 5.3 machine
# (I haven't checked)
#
# Another user reported that if he included those libraries, a large number
# of the tests failed (approx. 20-25) and he would get a core dump. To
# make things worse, test results were inconsistent, i.e., some of the
# tests would pass some times and fail at other times.
# The safest thing to do seems to be to eliminate them.
#
# Actually, the only libs that you want are '-lm'. Everything else
# you need is in libc. You do also need '-lbsd' if you choose not
# to use the -D_BSD_* defines. Note that as of 6.2 the only
# difference between '-lmalloc' and '-lc' malloc is the debugging
# and control calls. -- scotth@sgi.com
