Hi Brendan,

I've attempted without success, so far, to port bash to Mingw32.  I'm 
real interested in getting this accomplished so maybe we can work 
together.  The main problems are the fork and wait functions.  There are 
some other UNIX specific functions (you know, getuid, getgid, etc) that 
can be easily stubbed but there are some that cannot.

Also the inode value from the fstat and stat is always returned as zero.  
Don't blame Colin or JanJaap for that, that's the way that M$ designed 
the function; even though there is a file index number that could have 
been used.

I've been able to port to Mingw32 most of the fileutils, textutils, 
sh-utils, and grep.  As an aside to this, you know the problems about 
\r\n vs \n; well, with native compiled utilities, it seems that the 
default open will read \r\n or just \n and will write \r\n.

To execute configure I currently start the cygwin bash with my 
environment setup for cygwin, run configure, setup my environment for 
Ming or EGCS and execute make -i -k >& make.log, take care of errors and 
repeat the make process.  Occasionally I have to gcc by hand, which 
isn't too bad if you do it in bash.  Example:

export CFLAGS="-c -g -O2"
for file in `ls *.c`; do gcc $CFLAGS $file; done


In this way I am able to compile all programs with one command.

As for djgpp, they have a 16 bit version of bash, crippled with 8.3 
filenames.  They say they support long file names with special 
environment variables but I've never gotten it to work.

My ideas for fork is to emulate it by calling one of the spawn or thread 
functions (I haven't determined which might be better); for wait it is 
to emulate it by calling the _cwait function.  For lstat I #define lstat 
stat.  For the checking of inodes for the same file I am #ifndef 
__MINGW32__ ... #endif around the code; this means that for "cat 
thisfile > thisfile" you will end up with a zero length file, but, that 
is the way it works on AIX unix.
