Hi,
I have been able to build latest source of tesseract on cygwin.
ra@Shree ~/tesseract-ocr/tesseract
$ tesseract -v
tesseract 3.05.00dev-296-g60176fc
leptonica-1.73
libgif 4.1.6(?) : libjpeg 8d (libjpeg-turbo 1.4.2) : libpng 1.6.20 :
libtiff 4.0.6 : zlib 1.2.8 : libwebp 0.4.3
However, make training is failing with the following error:

This is with source as of latest commit:
commit 60176fc5ae5e7f6bdef60c926a4b5ea03de2bfa7
replace __CYGWIN32__ with __CYGWIN__
Has anyone else built the latest version on cygwin? What dependencies
and versions did you use?
Thanks!
Attached the two patches I used for 3.04.01,
I assume you need also for dev, but I have not tested.
Regards
Marco
