newcomer question: compiling gtk - memmove...

[Marcus Hertlein <mph gomez physics lsa umich edu>]

Hello,

I'm not sure this question really belongs here, but I don't know where
this would be most appropriate. So apologies...

My gcc compiler doesn't recognize the function "memmove", which gets 
called a few times in the gtk code (971201). Maybe this is a gcc problem?
Or do I need to include other libraries that the gtk configure script didn't 
find correctly?
My knowledge of gcc code (or gtk) is very limited, and I don't know how 
to figure out the complicated interdependencies of files... (Actually, I 
just wanted to install gtk to run gimp, not even program in it...)

On my computer, a sparc20 running SunOS 4.1.4, memmove doesn't exist, 
although the other things like memcpy and so on do. I'm confused, since 
other unix computers that I can log on to have different manpages, some 
including memmove with either string.h or memory.h, some not.

[...]

Any ideas as to what I might be doing wrong? Or workarounds?

Apologies if this doesn't belong here, but thanks for your help.
