[Development] qnetworkinterface_unix.o compilation error

[Gordon Marler]

I think the issue here is what standard you're (not) telling the Solaris 
Studio 12.3 compiler to conform to.

Try re-configuring using these arguments:

qt-everywhere-opensource-src-4.8.3/configure -prefix 
/your/path/of/choice -platform solaris-cc \
                                                                           -no-iconv -opensource -D_XOPEN_SOURCE=500 \
                                                                           -D__EXTENSIONS__ -confirm-license

The salient items are:

-no-iconv
     Doesn't seem to compile without this - a separate issue

-D_XOPEN_SOURCE=500
     Conform to SUSv2 standard (includes POSIX) - see standards(5) man 
page for details

-D__EXTENSIONS__
     Allow extensions that normally only fall under C99 (like the math 
functions ceil, floor, etc - see their man pages) to still be used, if
they don't conflict with SUSv2, without being forced to use Studio 
12.3's c99 compiler.  You'll note the man pages for those functions
all state that you have to use c99 to compile them.  This flag let's you 
escape from that requirement.

QT 4.8.3 compiles fine in it's entirety for me on S11 and S11.1 with 
Solaris Studio 12.3 after using those.  May also work on Solaris 10, but 
haven't bothered testing it.
