[geos-devel] GEOS 3.1.0

Libtool reversion!

libtool in GEOS 3.0.3 is 1.5.26

libtool in GEOS 3.1.0 is 1.5.16

This creates a problem compiling a multiple-architecture library on  
OSX - libtool is stripping out the -arch and -isysroot flags.  I  
believe libtool 1.5.20 is the minimum to support these OSX flags.

This was not a problem when I built 3.1 from SVN in November, r2230.

"We are at war with them. Neither in hatred nor revenge and with no  
particular pleasure I shall kill every ___ I can until the war is  
over. That is my duty."

"Don't you even hate 'em?"

"What good would it do if I did? If all the many millions of people of  
the allied nations devoted an entire year exclusively to hating the  
____ it wouldn't kill one ___ nor shorten the war one day."

<Ha, ha> "And it might give 'em all stomach ulcers."
