How to add extension to tightvnc during build?

I am trying to rebuild tightvnc on Archlinux to add needed extensions to match those in the opensuse tight vnc package.  Currently the Arch package has the following:

Arch:

number of extensions:    7
    BIG-REQUESTS
    MIT-SHM
    MIT-SUNDRY-NONSTANDARD
    SHAPE
    SYNC
    XC-MISC
    XTEST
default screen number:    0
number of screens:    1

openSuSE uses these:

number of extensions:    25
    BIG-REQUESTS
    DEC-XTRAP
    DPMS
    Extended-Visual-Information
    GLX
    MIT-SCREEN-SAVER
    MIT-SHM
    MIT-SUNDRY-NONSTANDARD
    RECORD
    RENDER
    SECURITY
    SGI-GLX
    SHAPE
    SYNC
    TOG-CUP
    VNC
    X-Resource
    XAccessControlExtension
    XC-APPGROUP
    XC-MISC
    XFree86-Bigfont
    XInputExtension
    XKEYBOARD
    XTEST
    XVideo
default screen number:    0
number of screens:    1

Where in the tightvnc build process to I specify these extensions??
