small not but i forgot i thinked to mention 
that (and some may comment on that if they want)

there is as far as i realize a confusion what 
to return from main, (and also what return on succes and what on error)
afair the present rule is to ret 0 on succes and everything alse on error.. (which is unfortunatelly negation of common rules used for normal functions which are opposite 0 on fail non zero for succes) i just propose to change it (i mean main return value meaning)

the proposition is: return positive value on succes (including zero as positive) and return any negative on error

(it assumes that any system in which c is used alows to return signed integers on return - buts probably mostly true (are there any system that would not provide signed numbers onlu unsigned?)
