float identifier has been already used

[Christopher Dimech]

I made the following macro to display an image.  I am encountering a problem
because when I want to display the image image a second time, the same float
identifier (name{igc03-sicl-circumambrg}) has been already used.


@macro igmSiclCircumambrg
@set fignm igc03-sicl-circumambrg [01]
@float Figure,igc03-sicl-circumambrg

  @center @image{@value{igc03-path}/igc03-01-sicl-circumambrg,12cm,,,.png}

  @paragraphindent 0
  @caption{@strong{Sites of the 102 seismic stations in Sicily and in
    its Circum-Ambient Regions for use in the microseismic analysis
    effort.}}

  @shortcaption{Sites of the 102 seismic stations in Sicily and in its
    Circum-Ambient Regions for use in the microseismic analysis effort.}

@end float
@end macro
