bug report on gcc port

[Clark Sims]

The following code fragment bombs the cygwin port of gcc:

#include <string>
#include <ctype.h>

std::string foo( const std::string& rhs);

std::string foo( const std::string& rhs) {
  std::string str = rhs;
  for (size_t i=0; i<str.size(); i++) {
    str[i] = ::tolower( str[i]);
  }
  return str;
}

gcc -c foo.cpp :
foo.cpp: In function `class string foo(const string &)':
foo.cpp:9: parse error before `__extension__'
foo.cpp:9: `__x' undeclared (first use this function)
foo.cpp:9: (Each undeclared identifier is reported only once
foo.cpp:9: for each function it appears in.)
foo.cpp:9: parse error before `)'

The code fragments works well in other compilers and other ports of gcc.
