The suncc shell script in /mit/sunsoft/sun4bin/suncc could be seriously
improved. Problems:
* It uses csh instead of sh, which is slower. (Also, it's in
general a better idea to write shell scripts using
/bin/sh in general.)
* Instead of executing the real cc program directly, it sets a
path and then tries to execute it. This is bad for two
reasons. First, setting a path under csh causes it to
scan all the directories in your path, which is slow.
(See above reason it being a bad idea to write csh
scripts.) Second, if /mit/sunsoft/sunwspro/cc doesn't
exist for some reason, very surprising things happen,
instead of getting an error message.
Enclosed please find a new and improved suncc script. I suggest that
/mit/sunsoft/sun4bin/suncc be replaced with the following script.
Thanks!!
