This question was answered in the cygwin list, but the proposed
solutions did not work.
Someone on the list suggested that I send the question to
cygwin-xfree, so I did.
When I delete the -I and the -L and try:
X_INCLUDES =
X_LIBS = /usr/include -lX11
I get:
g++ -O2 -o aplus.exe /usr/include mainC.o aplus_main.o aplus_uext.o
matherr.o -L/usr/local/aplus-fsf-4.22/src/IPC

When I also delete the /usr/include and try:
X_INCLUDES =
X_LIBS = -lX11
I get:

undefined reference to `_XWarpPointer'
I have tried numerous other variations.
The one that appears to work best is:
X_INCLUDES = /usr/include
X_LIBS = -L /usr/include/X11 \
but then I get errors with am__include
The Makefile was generated by Automake 1.6.3.
When I try to generate a new one, I get;
$ automake
automake: `configure.ac' or `configure.in' is required
As there is no configure.ac or configure.in
I am coming to the conclusion that I may need to learn Autotools and
construct a fresh build process.
