automake configure hangs on cygwin

[Chamila Wijayarathna]

Hello all,
I downloaded automake 1.14.1, extracted it and ran ./configure using cygwin.
It ran a while and hang at "checking for yacc".
Following is the output I got.

checking whether make supports nested variables... yes
checking build system type... i686-pc-cygwin
checking host system type... i686-pc-cygwin
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /usr/bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking whether ln -s works... yes
checking for perl... /usr/bin/perl
checking for tex... no
checking for yacc...

Any idea on how can I fix this?

Thank You!
