Autoconf scripts for configure and make.

Run "aclocal -I m4" and "autoconf" to create the configure script.
I checked this in to test the configure script.
Note: the generated Makefile is not supposed to work yet. Use the already checked in Makefile instead.

+// Configuration include file for @PACKAGE_NAME@ @PACKAGE_VERSION@
+// @PACKAGE_BUGREPORT@
+
+// Note on version comparison:
+// -------------------------------------------------------------------
+// Delphi (in contrast to FPC) DOESN'T support MACROS. So we
+// can't define a macro like VERSION_MAJOR(version) to extract
+// parts of the version-number or to create version numbers for
+// comparison purposes as with a MAKE_VERSION(maj, min, rev) macro.
+// So we have to define constants for every part of the version here.
+//
+// In addition FPC (in contrast to delphi) DOESN'T support floating-
+// point numbers in $IF compiler-directives (e.g. {$IF VERSION > 1.23})
+// It also DOESN'T support arithmetic operations so we aren't able to
+// compare versions this way (brackets aren't supported too):
+//   {$IF VERSION > ((VER_MAJ*2)+(VER_MIN*23)+(VER_REL*1))}
+//
+// Hence we have to use fixed numbers in the directives. At least
+// Pascal allows leading 0s so 0005 equals 5 (octals are
+// preceded by & and not by 0 in FPC).
+// We also fix the count of digits for each part of the version number
+// to 3 (aaaiiirrr with aaa=major, iii=minor, rrr=release version)
+//
+// A check for a library with at least a version of 2.5.11 would look
+// like this:
+//   {$IF LIB_VERSION >= 002005011}
+//
+// If you just need to check the major version to this:
+//   {$IF LIB_VERSION_MAJOR >= 23}
+//
+// PLEASE consider this if you use version numbers in $IF compiler-
+// directives. Otherwise you might break portability.
