In case $(schemas_in_files) is known at configure time:

configure.ac:
mydatafiles=`echo "$schemas_in_files" |
             sed 's/.schemas.in$//;$program_transform_name;s/$/.schemas/'`
AC_SUBST([mydatafiles])

Makefile.am:
schemas_DATA = @mydatafiles@


Otherwise, I don't see a way to do this portably ATM.

Cheers,
Ralf
