Subject: freopen() problems


The following code works on at least one persons system.
On mine, the freopen() call for one stream wipes out the other.
If I uncomment the second pair, all the reads/writes work fine.

This is a win98 system.
I'v upgraded to 2.95 versions of gcc and mingw-extras
I'm not geting the cygwin.dll by mistake.
I'm using -mwindows, and -mno-cygwin.

I'm at my wits end.  
I will be most grateful for ideas about what's left to double check?
