Re: gzip converts stuff to 8.3 filenames

[Allan Peda <allan at interport dot net>]

I decided to write a little executable to convert those 8.3 programs
back again.  
I thought w32fn (for win32filename) would be an okay name.

It takes the 8.3 name on the command line and spits out the longname on
stdout.  For what it's worth I'm sending it out.

Two questions however:

1.)  I compiled it under MS VC++ (cheapo $35.00 edition).  If I wanted
to compile with cygwin or mingw32 would it be a big deal (uses / needs
windows.h)

2.) How best to incorporate this into the "sento" explorer folder?  As I
mentioned, it uses stdout.  Can I do pass these args with with cmd.exe? 
Or do I need to use:

explorer -> cmd.exe -> bash -> gzip.exe

Isn't that overkill?

Code attached (exe available if you want):
