Problems compiling ddd-3.3 on sparc Solaris 2.7/8 with gcc 3.0.2

[Rainer Dörntge]

Hi,

I encountered two problems on sparc solaris machines running
Solaris 2.7 resp. 2.8 while trying to compile ddd-3.3 with
gcc version 3.0.2.

The first one is in strclass.C, line 1434, which reads
<------------- SNIP ------------->
    int new_state = s.rdstate();
<------------- SNAP ------------->
I changed that to
<------------- SNIP ------------->
#if defined(__GNUC__) && __GNUC__ >= 3
    std::ios::iostate new_state = s.rdstate();
#else
    int new_state = s.rdstate();
#endif
<------------- SNAP ------------->
which works.

Btw., gcc 3.0.2 generates a lot of warning in strclass.h on solaris:
<------------- SNIP ------------->

<------------- SNAP ------------->

The second problem is in PannedGE.C at end of pannedGraphEditClassRec
and since I'm not familiar with libXt, I have no clue how to fix it:
<------------- SNIP ------------->
PannedGE.C: At global scope:
PannedGE.C:143: cannot convert `void (*)(...)' to `void (*)()' in 
   initialization
<------------- SNAP ------------->

Since I have not found these in PROBLEMS or BUGS, hopefully, I do not
annoy you too much :-)

Thanks,
Rainer
