Thanks for the information. The code lists directory and files names. It
does not list the file sizes.

Apparently the current MinGW library does not support'stat64' or
'_stat64' functions needed to read 64 bit filesize information from
structure 'stat' or 'stat64' ->st_size member.

How can I use with MinGW _stat64 and if necessary, _findfirst64,
_findnext64, _findclose, etc. and thereby avoid porting about 10,000
lines of Linux code to Visual Studio 10 and paying $ 1000's for a
license to give away the finial software for free?
