* winsup.h: take out protections of environ, errno, allow C use * *.cc: put winsup.h before other headers (for __INSIDE_CYGWIN__); use cur_environ() instead of just environ * times.cc: remove import protections * glob.c: add winsup.h * localtime.c: ditto * smallprint.c: ditto * Makefile.in: don't __INSIDE_CYGWIN__ as it messes up profiling.
