Ant version detection

Hello,

this is the first time I am dealing with the Postgres source.
Therefore, I am hoping this is the right place to propose
a patch.

The patch is to be applied to the current CVS source.

This is it:

Index: configure
===================================================================
RCS file: /projects/cvsroot/pgsql-server/configure,v
retrieving revision 1.306
diff -r1.306 configure
3190c3190
< if "$ANT" -version | sed q | egrep -v ' 1\.[5-9]| [2-9]\.' >/dev/null ; then
---
> if "$ANT" -version | egrep '^Apache Ant version' | sed q | egrep -v ' 1\.[5-9]| [2-9]\.' >/dev/null ; then
Index: src/interfaces/ecpg/preproc/preproc.y
===================================================================
RCS file: /projects/cvsroot/pgsql-server/src/interfaces/ecpg/preproc/preproc.y,v
retrieving revision 1.262
diff -r1.262 preproc.y
5250a5251
> ;

The first one is a fix in the detection of the ant version. Some newer
versions of ant echo the CLASSPATH variable before printing the version
number. That behaviour breaks the version detection. Therefore, only lines
beginning with "Apache Ant version" should be considered.

The second one is a missing semicolon. I am not familiar with the bison
syntax - but imho that semicolon _is_ missing.

Kind regards,

Johann Uhrmann
