$USER is a Windows environment variable and Cygwin doesn't change it.
It just reports what Windows says.

I disagree that Cygwin should normalize it to lower case by default.

You can do something creative with your logon process by sending the
variable to some shell script and having it fix the case.

I don't write bash scripts or awk so here is an example in perl.

=-=-=-=-=-=-=-=-=-=-=-=-= code =-=-=-=-=-=-=-=-=-=-=-=-=
#!/usr/bin/perl -w
$word = shift;
print " In: $word\n";
$word =~ s/([A-Z])/lc($1)/ge;
print "Out: $word\n";

Examples of output:
37067 AT HOST ~
$ ./test3.pl DSmiley
 In: DSmiley
Out: dsmiley
37067 AT HOST ~
$ ./test3.pl DSMILEY
 In: DSMILEY
Out: dsmiley
37067 AT HOST ~
$ ./test3.pl dsmiley
 In: dsmiley
Out: dsmiley
37067 AT HOST ~
$
