Subject:	_impure_ptr error mesage
Mime-Version:	1.0

     I have installed gcc-2.95 separate from Cygwin-b20.1 and have been
experiencing problems using it instead of the b20.1 gcc.  Does anyone know the
meaning of the error message "undefined reference to _impure_ptr" which seems
to appear for me using gcc-2.95 with "-mno-cygwin" when I have used code that
references things like getchar, putchar, getc (but not fgetc), putc (but not
fputc), stdout and stderr.  Could it mean that these things are included in
Cygwin but not the latest port of Mingw?  That would be wierd!  Is it possible
I need a #include<whatever.h> in my code?
