* *.c: add space after commas everywhere. * *.c: use SCM_VECTOR_SET everywhere, where a vector is written. Document cases where SCM_WRITABLE_VELTS() is used. * vectors.h (SCM_VELTS): prepare for write barrier, and let SCM_VELTS() return a const pointer (SCM_VECTOR_SET): add macro. * autogen.sh (mscripts): find and check version number of autoconf. Complain if 2.53 is not found.
