Hi all...

Just compiled povray-3.50c on my debian linux box and notized 
the following: 

----------<snip>---------
checking for size_t... yes
checking whether time.h and sys/time.h may both be included... yes
checking whether struct tm is in sys/time.h or time.h... time.h
checking for working memcmp... no
checking return type of signal handlers... void
checking for strftime... no
checking for strftime in -lintl... no
checking for vprintf... no
checking for getcwd... no
checking for gettimeofday... no
------------------------

The last line definitively made me suspicious. 

The problem begins when detecting -lX11: For X11 detection 
the linker path -L/usr/X11R6/lib is passed but it is omitted for 
all future calls to gcc. The following patch fixes this problem:

	Wolfgang,

	Could you try the configure script I posted last februray in
p.unix ? -- actually a small package to be downloaded from:
	http://pov4grasp.free.fr/download/povray-3.50c-config.tar.gz

	Since the order of the checks have been changed, I don't have
this problem you mention (i.e. w/o adding the -L$x_libraries of your patch).
I'd like to know if my mods work for you. I didn't update this package since
I posted it {shame on me}, so it would be a good reason  :-)

	BTW, I guess this post and the other one about src/conf.h would
better fit in p.unix since this is only related to the UNIX/Linux version.
	Followup-to to p.unix.

	- NC
