[Bug c++/33793] New: global scoping for htons/htohs fails (::htons)

[amit dot khandelwal at lehman dot com]

GCC version: 3.2.3
Host: Linux

Sample code.

#include <netinet/in.h>

int main()
{
unsigned short t;
::htons(t);
return 0;
}

/usr/bin/g++ -O2 t.cpp
t.cpp: In function `int main()':
t.cpp:10: syntax error before `__extension__'
t.cpp:10: `__x' undeclared (first use this function)
t.cpp:10: (Each undeclared identifier is reported only once for each function
it appears in.)
t.cpp:10: `__v' undeclared (first use this function)
t.cpp: At global scope:
t.cpp:10: syntax error before `)' token

If I don't use -O2 the code compiles. If I change ::htons to htons the code
compiles even with -O2. Why does it fail for ::htons()

htons is a macro, use parens or #undef to suppress it.
