Subject: update to 5.003_97b/hint/irix_6_2.sh
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=4e5f255bc79a4d332832eda907f7e26f656b7ec2;p=p5sagit%2Fp5-mst-13.2.git

update to 5.003_97b/hint/irix_6_2.sh

It is possible with the 7.1 compilers for IRIX-6.2 and later to
change the default compiler options for the system.  You need to
explicitely select the compiler options in the hints file to avoid
mix-n-match ABI problems.  I also added some additional commentary...
Patch against 5.003_97b follows:
