+Initial Package Version: 5.20.2

+
+    Fix Errno.pm generation for gcc-5.0
+    
+    gcc-5.0 -E interleaves now line numbers with expended macros, so that
+    the generated errno.c will be preprocessed to
+    
+    EBFONT => [[
+               59
+                    ]]
+    
+    which is hard to parse in in line-based reader.
+    
+    So use -P option with gcc >= 5.0. Global -P usage would break makedepend,
+    global -ftrack-macro-expansion=0 would break lib/h2ph.t.

+    h2ph: correct handling of hex constants for the preamble

+    Previously they were treated as identifiers resulting in code

+    
+    We also try to prevent compile-time warnings from large hex integers,

+      PicoC is a very small C interpreter for scripting. It was originally
+      written as a script language for a UAV's on-board flight system. It's
+      also very suitable for other robotic, embedded and non-embedded
+      applications. The core C source code is around 3500 lines of code. It's
+      not intended to be a complete implementation of ISO C but it has all the
+      essentials. When compiled it only takes a few k of code space and is also
+      very sparing of data space. This means it can work well in small embedded
+      devices.
