Summary:                    Can't compile on Cygwin:
Description: 
In compiling from the sources on Cygwin (setup version 2.871) "make" gave me an
error in sort_r: "Cannot detect operating system".


Steps to Reproduce: 
$ make
...
/bin/sh ../libtool  --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I.  
-DLIBRDFA_IN_RAPTOR -I../librdfa -DRAPTOR_INTERNAL=1 -I/usr/include/libxml2   
-O2 -march=native -pipe -MT sort_r.lo -MD -MP -MF .deps/sort_r.Tpo -c -o
sort_r.lo sort_r.c
libtool: compile:  gcc -DHAVE_CONFIG_H -I. -DLIBRDFA_IN_RAPTOR -I../librdfa
-DRAPTOR_INTERNAL=1 -I/usr/include/libxml2 -O2 -march=native -pipe -MT sort_r.lo
-MD -MP -MF .deps/sort_r.Tpo -c sort_r.c  -DDLL_EXPORT -DPIC -o .libs/sort_r.o

Additional Information: 
Appending the line after line 29 of src/sort_r.h fixed the problem:

defined __CYGWIN__ || \

i.e. accepting Cygwin as another variant of Linux-like system.
