[sldev] cygwin flex lscript_compile workaround

[wuhanzymail]

How to apply below patch to indra.l? Just copy and paste these code to the end of indra.l? I tried but failed.
 
I have no experience about it, so could anyone kind to give more detail instructions? Thank you so much!
 
Best Regards,
Ying

I'm not sure whether this has already been addressed here, but we 
discovered a problem with the latest version of Cygwin flex and 
lscript_compile and I thought I would share the workaround. We've 
committed the workaround to our release-candidate branche so it should 
be in an upcoming source drop as well.

1. Add "YY_NO_UNISTD_H" to the list of Preprocessor Definitions in the 
lscript_compile project file.
2. Apply the following patch it indra.l:
