The process is described below. Standard identifiers are okay, it's
only the global non-standard identifiers that look like standard
identifiers (have a single leading _) that pollute the namespace. 

$ cat a.c
int main( void )
{
	return 0;
}
$ gcc -ansi -pedantic a.c
$ nm -g a.exe | cut -c10- | grep '^.._[^_]' > dg

Edit dg and manually delete all the Standard C identifiers.
Paste into post and edit to taste.
