If I link wxWidgets 2.8 into multiple .DLL files, the link speed is very fast,
here is the details (the last 2 columns were reported by ld '--stats'):

DLL SIZE       FILE NAME                LD TIME     LD DATA SIZE
   1991K   wxbase28u_gcc.dll              42.56s    524M
    214K   wxbase28u_net_gcc.dll           0.29s     49M
    194K   wxbase28u_odbc_gcc.dll          0.20s     32M
    244K   wxbase28u_xml_gcc.dll           0.15s     18M
    831K   wxmsw28u_adv_gcc.dll            1.06s    102M
    481K   wxmsw28u_aui_gcc.dll            0.62s     82M
   5028K   wxmsw28u_core_gcc.dll         349.60s   1694M
    109K   wxmsw28u_dbgrid_gcc.dll         0.18s     39M
    108K   wxmsw28u_gl_gcc.dll             0.22s     44M
    632K   wxmsw28u_html_gcc.dll           0.95s     78M
    190K   wxmsw28u_media_gcc.dll          0.29s     32M
    166K   wxmsw28u_qa_gcc.dll             0.24s     28M
   1226K   wxmsw28u_richtext_gcc.dll       1.64s    102M
    571K   wxmsw28u_xrc_gcc.dll            0.68s     60M

  11740K            -                    398.68s   2884M

The total time is about 400s, why when they link into single .DLL file use so
much memory (4.6GB) ? and not finished after 6 hours CPU (sys + user) time ?
