   Is there some reason why this is a bad idea? 


I compiled it and ran it on a sun4 using CC as well as cc.  It ran as
expected.  However it failed to run under gcc:

[pacific]>gcc test.c
test.c: In function main:
test.c:8: `foo' undeclared (first use this function)
test.c:8: (Each undeclared identifier is reported only once
test.c:8: for each function it appears in.)
[pacific]>   

So does this mean there is a bug in gcc?
