Hi Mattia,

Thanks for replying to my message: (see below)

I am not certain what was used for wxGTK, since I downloaded it from
http://freeware.sgi.com/index-by-alpha.html.  This is pre-packaged
installable distribution.  I would imagine that it was compiled with
CC.  SGI has three compilers cc, CC and c89.

It is a C++ compiler (that can also handle C).

I am certain that it is treating the file as C++.  When I tried "cc"
(instead of CC) it gave bunch of errors such as:

cc-1020 cc: ERROR File = /usr/local/include/wx/defs.h, Line = 456
  The identifier "class" is undefined.

  class WXDLLEXPORT wxObject;
  ^

This is clearly a c verses c++ issue.  However, when I use CC, then I
get bunch of errors that all seems to be related to SvREFCNT_inc, SvOK,
SvUV, SvPV_nolen, etc.  In fact the first 40 errors all include the
mentioned names, all with the same message:

  A pointer to an incomplete class type is not allowed.

I did, with no effect.  Any other suggestions?

Thanks again.
