+## Changes to Build System
+
+### Change CFLAGS, CPPFLAGS, CXXFLAGS, and AFLAGS from Recursive to Simple
Assignment
+
+[PR-1890](https://github.com/apache/incubator-nuttx/pull/1890)
+(commit
[2caf3a69e3d60ec550980f7ba897c732e7a39df7](https://github.com/apache/incubator-nuttx/pull/1890/commits/2caf3a69e3d60ec550980f7ba897c732e7a39df7))
+attempts to speed up compilation time for concurrent builds by changing
+assignment to makefile variables `*CFLAGS*`, `*CPPFLAGS*`, `*CXXFLAGS*`, and
+`*AFLAGS*` from recursive `=` to simple `:=`. This causes these compile
+options to be expanded only once during the build.
+
+If you are using NuttX on a custom board not in the NuttX repository, you may
+want to make a similar change to your `Make.defs` files. Change these
+recursive assignments:
+
+```
+CFLAGS = $(ARCHCFLAGS) $(ARCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS)
$(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
+CXXFLAGS = $(ARCHCXXFLAGS) $(ARCHWARNINGSXX) $(ARCHOPTIMIZATION)
$(ARCHCPUFLAGS) $(ARCHXXINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
+CPPFLAGS = $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS)
+AFLAGS = $(CFLAGS) -D__ASSEMBLY__
+```
+
+to simple assignments:
+
+```
+CFLAGS := $(ARCHCFLAGS) $(ARCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS)
$(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
+CXXFLAGS := $(ARCHCXXFLAGS) $(ARCHWARNINGSXX) $(ARCHOPTIMIZATION)
$(ARCHCPUFLAGS) $(ARCHXXINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
+CPPFLAGS := $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS)
+AFLAGS := $(CFLAGS) -D__ASSEMBLY__
+```
+
+### Not Necessary to Define `__NuttX__` in Make.defs
+
+[PR-2192](https://github.com/apache/incubator-nuttx/pull/2192)
+(commit
[9208176f600d0d04446531909bf05710716a5ee4](https://github.com/apache/incubator-nuttx/commit/9208176f600d0d04446531909bf05710716a5ee4))
+refactors definition of the `__NuttX__` preprocessor symbol to
+`tools/Config.mk`, so it is no longer necessary to define it in each board's
+`Make.defs` file.
+
+If you are using NuttX on a custom board not in the NuttX repository, you may
+want to make a similar change to your Make.defs files.
+
+Remove lines like this:
+
+```
+ARCHDEFINES = -D__NuttX__
+```
+
+Or remove -D__NuttX__ from lines like this:
+
+```
+CXXFLAGS += $(ARCHDEFINES) $(EXTRAFLAGS) -pipe -std=c++11 -D__NuttX__
+```
