Hhhm...
My man page(ver 4.0.0) says this:
.PP
.I data-expression-1 \fB~=\fR \fIdata-expression-2\fR
.I data-expression-1 \fB~~\fR \fIdata-expression-2\fR
.RS 0.25i
.PP
The \fB~=\fR and \fB~~\fR operators (not available on all systems) perform
extended regex(7) matching of the values of two data expressions, returning
true if \fIdata-expression-1\fR matches against the regular expression
evaluated by \fIdata-expression-2\fR, or false if it does not match or
encounters some error.  If either the left-hand side or the right-hand side
are null, the result is also false.  The \fB~~\fR operator differs from the
\fB~=\fR operator in that it is case-insensitive.

And I don't get any syntax errors when I use ~=.
