compilation error in fltkflatview.cc

Greets all,

As I've mentioned previously I'm trying to compile
dillo-3.0.3 on Silicon Graphics using the SGI MIPSpro
compiler. I'm doing this for a large group of SGI users who
reside at nekochan.net. The compilation fails in line 884 in
fltkflatview.cc:

----------
cc-3168 CC: ERROR File = fltkui.cc, Line = 884
  A name followed by "::" must be a class or namespace name.

  bool

       ^

2 errors detected in the compilation of "fltkflatview.cc".

I suspect it needs a 'using namespace' or somesuch here,
thoughts?

Thanks a bunch!
