This error is still in there as of 3.3.3 and appears under Solaris 9 as
well.  I'm not sure why HAVE_NETDB_H isn't being properly set; however, 6
hours into a compile is not a good time to crash out - the little stuffed
dust puppy I had in my hand at the time almost didn't survive...

As Dan points out, grep didn't show the whole
story.  I still don't understand the code well
enough to explain it, but I did get gcc to build
by just inserting the 
#define MAXHOSTNAMELEN  256
line in the natInetAddress.cc file.  Thanks for
your consideration,

gcc-3.3.1 build problem MAXHOSTNAMELEN undeclared

[Becky Sander]

Good morning,
I'm having problems building gcc3.3.1 on solaris
2.7.  This same error is posted twice to the gcc
mailing list about a year ago, but I don't see a
resolution posted.  Has anyone figured this out?

I've added /usr/include with CPPFLAGS environment
variable, but the build still crashes here.  And,
I can't seem to locate where buffer is defined,
either. I'm completely stuck.  Any suggestions are
greatly appreciated!
