wxWidgets 3.0.3

[Simon Jensen]

Dear group.

I try to compile wxWidgets 3.0.3 on Solaris 10 and have problems.
configure ends up with this output:

Configured wxWidgets 3.0.3 for `sparc-sun-solaris2.10'

  Which GUI toolkit should wxWidgets use?                 GTK+ 2
  Should wxWidgets be compiled into single library?       no
  Should wxWidgets be linked as a shared library?         yes
  Should wxWidgets support Unicode?                       yes (using
wchar_t)
  What level of wxWidgets compatibility should be enabled?
                                       wxWidgets 2.6      no
                                       wxWidgets 2.8      yes
  Which libraries should wxWidgets use?
                                       STL                no
                                       jpeg               sys
                                       png                builtin
                                       regex              builtin
                                       tiff               sys
                                       zlib               sys
                                       expat              sys
                                       libmspack          no
                                       sdl                no

After a while make (using gcc 5.5) stops with this fault:

=> Can someone give me a hint?
