Questionable C/C++ statement

[Eljay Love-Jensen]

Hi Dave,

GCC's g++ found some errors in the code, for me.

--Eljay

$ g++ -pedantic -W -Wall questionable.cpp
question.cpp: In function `void foo()':
question.cpp:7: error: ISO C++ forbids variable-size array `buf'
question.cpp: In function `int main(int, char**)':
question.cpp:22: warning: unused parameter `int ac'
question.cpp:22: warning: unused parameter `char**av'

$ g++ --version
