+/* acconfig.h
+
+   Descriptive text for the C preprocessor macros that
+   the fptools configuration script can define.
+   The current version may not use all of them; autoheader copies the ones
+   your configure.in uses into your configuration header file templates.
+
+   The entries are in sort -df order: alphabetical, case insensitive,
+   ignoring punctuation (such as underscores).  Although this order
+   can split up related entries, it makes it easier to check whether
+   a given entry is in the file.
+
+   Leave the following blank line there!!  Autoheader needs it.  */
+
+
+/* The following definitions will only work on Linux.
+   I (ADR) make no apology for this because we SHOULD NOT
+   be using system based tests and I want to get this puppy running
+   tonight.  I'm forced to define these values here because the
+   current system contains 2 (two) config.h files - both of
+   which are needed.  Will someone at Glasgow please fix this mess. */
