Not exactly. I used a struct __sFile_fake for each one of 
stdin/out/err, like in newlib/libc/include/sys/reent.h.

I did this after I compiled a simple C application with the -E 
flag (only preprocessing) and I saw that stdin/out/err were 
translated to _impure_ptr->_stdin/out/err. I searched for these 
symbols in newlib and I found them in reent.h.

I don't know how accurate and right is it, but it seems to link 
the application ok.
