 104 <p>So, to me, the ECRs that changed between the CVS tags of Lion_com3_2_2_120204 and Lion_com3_2_2_121604 WRT src/ChangeLog.lynx would be</p>
 105
 106 <ol>
 107   <li>23084</li>
 108   <li>22875</li>
 109   <li>22805</li>
 110 </ol>
 111
 112 <p>(I assume that ECR #22989 was included with the previous toolchain).</p>
 113
 114 <p>Or am I just looking at this the wrong way?</p>
 115
 116 <p>Futhermore, the other files associated with, for example, ECR #22875, are:</p>
 117
 118 <ul>
 119   <li>toolchain.cvsr/src/gdb/gdbtypes.h: 1.2.4.1</li>
 120
 121   <li>toolchain.cvsr/src/ChangeLog.lynx: 1.25.2.30</li>
 122   <li>toolchain.cvsr/src/gdb/gdbtypes.c: 1.2.4.1</li>
 123   <li>toolchain.cvsr/src/gdb/config/i386/tm-i386lynx.h: 1.2.4.3</li>
 124 </ul>
 125
 126 <p>Yet, other than ChangeLog.lynx, all other files have tags that suggest that nothing else changed! For example, gdbtypes.h has Lion_com3_2_2_120204 pointing to revision 1.2 and Lion_com3_2_2_121604 also pointing to 1.2! Likewise for gdbtypes.c and config/i386/tm-i386lynx.h. Is this a tagging error?</p>
