Alsa-lib compilation error

Alsa-lib compilation error

[Caio Lima]

Hello ALSA-devel team, nice to contact you. Firstly I want to let you know
I'm a fan of the work of you guys of the ALSA Project, specifically of the
alsa-lib of which I had a little experience.
I'm needing help with the compile of the alsa-lib library, I'm using cygwin
and following the instructions in the "INSTALL" file inside the source but
during the compiling with the command "./gitcompile" I'm getting some
errors, here the entire log:
