[geos-devel] automake/conf/aclocal

[David Blasby]

I tried again on a different linux machine here, unfortunately with the 
same wrong results.

[dblasby at lion work_dave]$ rm *.o test
[dblasby at lion work_dave]$ ./make_it
geom text (to be parsed norman):POLYGON((100 200,100 140,180 140,180 
200,100 200))

geom (WKTWriter):POLYGON ((100.0000000000000000 200.0000000000000000, 
100.0000000000000000 140.00000000
00000000, 180.0000000000000000 140.0000000000000000, 
180.0000000000000000 200.0000000000000000, 100.000
0000000000000 200.0000000000000000))

result in C (norman) is
POLYGON ((100.0000000000000000 200.0000000000000000, 
100.0000000000000000 140.0000000000000000, inf inf
, inf inf, inf inf))
