charset/iconv/iconv.go need //#include <errno.h>

[GoogleCodeExporter]

What steps will reproduce the problem?
 On Mac OS X, hg clone, cd charset/iconv, make -k

What is the expected output? What do you see instead?
make -k 
CGOPKGPATH=go-charset.googlecode.com/hg/charset cgo --  iconv.go 
error: 'EILSEQ' undeclared (first use in this function)
error: (Each undeclared identifier is reported only once
error: 'EINVAL' undeclared (first use in this function)
error: 'E2BIG' undeclared (first use in this function)
unresolved names
make: *** [_obj/_cgo_run] Error 2
make: Target `all' not remade because of errors.

What version of the product are you using? On what operating system?

Please provide any additional information below.

Add the following line to iconv/iconv.go will fix the problem:

//#include <errno.h>

BTW, need to change os.ErrorString into os.NewString on L132 of iconv.go to 
make it gomakable.
