OK... I think the -woff 3970 issue is resolved. The warning is not
inhibited, since it does not exist, when I use the 7.4 compiler (I
tested this with the 2.8.3 wxGTK distribution) and it is inhibited
when I use the 7.4.4m compiler (I tested this with the 2.8.3 wxX11
distribution).

Now... when I tried to make my wxGTK distribution (with the 7.4
compiler) I no longer got the error I had previously regarding
strtoull. Was a new version of "configure" all I needed? I think you
mentioned I might have needed other files as well (Makefile, etc). If
not, great... I can now move forward.

So... I got further in the make... but I died in a later part of the
build process with an C compiler error that stated a "declaration
cannot come after an executable statement in a block". That's odd, I
thought C99 allowed this, but perhaps the MIPS compiler does not use
C99 by default? Anyway, I checked the doc and found a "-c99" switch to
the C compiler and tried again (perhaps this should be documented in
the install.txt file under the "Building with SGI" section?).

Now I died in the compilation of src/common/config.cpp. I got the
following message:

It looks like the configure process found a "round" function by using
a test C program (with the -c99 switch) and wx/math.h is indeed a C
header. But it appears that using wx/math.h in a C++ program might be
a problem (on IRIX anyway), since "round" is not defined when using C+
+. The IRIX header file /usr/include/internal/math_core.h has the
following declarations:

__________

#if defined(__c99)
extern double      round(double);
extern float       roundf(float);
extern long double roundl(long double);

#pragma optional   round
#pragma optional   roundf
#pragma optional   roundl
#endif /* __c99 */

Do you think the configure command file might need to be modified
again to fix this?
