build errors (error: conflicting types for 'yyget_leng')

[Andrew Milkowski]

Hi there

using latest git clone from git clone git://git.sv.gnu.org/guile.git
made an attempt to build with the following script
(all dependencies are resolving, error occurs at the install phase)

thanks for any guide in this!
