+
+    Support compress files with maxbits < 12
+    
+    The compress decompression code used by libXfont rejects valid archives
+    with maxbits less than 12 (compress allows values 9 - 16, 16 is the
+    default).  This is because maxbits-12 is used as index to hsize_table[].
+    
+    That looks like an incorrect port of the original compress code, where:
+    - hsize depended on BITS, the maximum maxbits value supported by particular
+      build, rather than on maxbits value from the particular input file
+    - the same hsize was used for all BITS <= 12
+    
+    The quick way to verify the problem is:
+      compress -b 11 fontfile.bdf
+      bdftopcf -o /dev/null fontfile.bdf.Z
+    which fails, while 12-16 works correctly.
+    
+    This fix removes hsize_table and uses 1 << maxbits (aka maxmaxcode) as
+    tab_prefix size.  As decompression code does not use hashing as compression
+    code, there does not seem to be a reason to allocate any extra space.
+    
+    Note: In this fix, maxbits == 9 is still rejected early.  AFAICS compress
+    is able to generate such files (unknown how correct such output is), but is
+    unable to uncompress them correctly.
