Branches: MAIN
CVS tags: HEAD
fixed bug in resize ("0 n resize" is now equivalent to "n allocate")
added primitives call-c and strerror
most primitives producing iors now produce error numbers derived from OS error
  numbers (EAGAIN and its kin)
.error now prints OS error messages for OS-derived error numbers.
primitives working with ferror now call clearerr
added a bit of documentation to glocals.fs to satisfy TeX
added definition of CC to Makefile.in again
