However, this IS the appropriate list for discussing the issue. Please, feel free to post examples and/or patches of what you think can be improved, rather than assuming, pessimistically, that we don't care to hear what you have to say. Furthermore, I don't see this claim written in the manual, which means that while it may have been one of the justifications provided at the time the default was set, it does not necessarily remain the justification used today for keeping that default. Personally, I still think that a default of -g for non-gcc is still appropriate - in this day and age, disk space is relatively cheap, and leaving debugging symbols in speeds development. And the Autoconf manual is quite clear that the user is free to specify CFLAGS to override the autoconf defaults, including via a config.site file to make this user preference automatic for all projects on that machine. So while the default of -g may not be your preference, I hope that it is still configurable enough that you do not feel locked into that default. And if there is something we could do to make the documentation more clear on this point, again, discussion or patches are welcome. - -- Don't work too hard, make some time for fun as well!
