Go to the prefences page "C/C++ -> Editor", and tick "Insert space for tabs".
Now open a C source file, indent somewhere, type "switch", hit CTRL+Space,
and choose to insert a switch-case-statement.

Now inspect the characters that have been inserted for indentation.
You only find tabs. Those that came from the template itself are OK, but
those that indent the whole template to fit the rest of the code should be spaces.

Suggestion:
In package org.eclipse.cdt.internal.corext.template.c you find CFormatter.java.

in method "private void indent", change

to

StringBuffer mystringbuf = new StringBuffer();

     mystringbuf.append ( ' ' );

indent = mystringbuf.toString();
}

	indent = Strings.createIndentString(fInitialIndentLevel);
