bcftools make fails with numerous vcfmerge errors in win10

Question

I want to compile latest github bcftools but I get these errors below.

[Install instructions]https://raw.githubusercontent.com/samtools/bcftools/develop/INSTALL mentions:

git clone git://github.com/samtools/htslib.git
git clone git://github.com/samtools/bcftools.git
cd bcftools
make

Also, I did the following:

1. BCFTOOLS_PLUGINS=/path/to/bcftools/plugins (added to Makefile) and these 3rd party libraries (downloaded and added to path)
2. zlib, gsl and libperl

ERRORS when make command runs
