           Summary: Compile error on Solaris 8 - kdecore/fakes.c has a
                    conflicting type for unsetenv
           Product: kdelibs
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Solaris
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: coolo kde org
        ReportedBy: stevee zuken co uk


Version:           3.90.1 (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 3.4.6 
OS:                Solaris

This is with version 3.90.1

I get this compile error on Solaris 8:

[  1%] Building C object kdecore/CMakeFiles/kdecore.dir/fakes.o
/cad4/stevee/kde_build/kdelibs-3.90.1/kdecore/fakes.c:77: error: conflicting types for 'unsetenv'
/cad4/stevee/kde_build/kdelibs-3.90.1/kde-build/kdecore/kdefakes.h:96: error: previous declaration of 'unsetenv' was here
/cad4/stevee/kde_build/kdelibs-3.90.1/kdecore/fakes.c:77: error: conflicting types for 'unsetenv'
/cad4/stevee/kde_build/kdelibs-3.90.1/kde-build/kdecore/kdefakes.h:96: error: previous declaration of 'unsetenv' was here

The prototype specifies unsetenv's return type as int but the definition has a return type of void. As the Linux version of unsetenv returns int I have changed the function to have a return type of int and return 0 on success or -1 on error. This allows it to compile.
