Which means a pile of badly written programs. 

 
That is why I said it was a bad idea for gcc to have "-fcommon" as
the default.  It is a real shame that it took so long to change it.
 
However, while that default meant that some people wrote C code with
a misunderstanding of linkages and the difference between
declarations and definitions, most C programmers don't make that
mistake.  When gcc eventually changed the default, it did not lead to
wide-spread breakage of code.
 

I wouldn't be so sure.
I have no statistics, but would expect that very significant part of
Unix-only C programmers, especially grumpy old timers, believes that
'-fcommon' is the real C and the rest are heresies.
