Compile problems with gnome-libs-0.99.7

[Rob Naccarato <rob naccarato sheridanc on ca>]

Platform: Linux 2.2.1, glibc 2.0.7, egcs egcs-2.90.29.

I can't seem to get gnome-libs-0.99.7 compiled. I get this failure
message:

orbitgtk.c:73: parse error before `gnome_ORBit_request_validate'
orbitgtk.c:76: warning: return-type defaults to `int'

As well, during the compilation, I tend to get these messages:

*** Warning: This library needs some functionality provided by -lz.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have.

This I can't understand, as I have all the libraries installed...
Any hints would be welcome.

Thanks.
