Recent changes to configure.in (and configure) break Solaris 5.6

[Richard Bollinger]

Recent changes to configure.in (and configure) break building Samba CVS on Solaris 5.6

    checking whether cc accepts -fpic... no
    ./configure: test: unknown operator -xO4

Several instances of the following code occur, which breaks when PICFLAG contains multiple tokens:
    if test x$PICFLAG = x; then

The obvious fix...
    if test "x$PICFLAG" = x; then

...gets us a lot further, but there are still problems compiling / linking winbind:

File actually created at last "Linking" step was apparently nsswitch/winbind_nss.po.o ... but I'm
lost in the Makefile at this point...

Help!
