I was thinking that, as part of SnzPrune's long overdue first
birthday celebrations, I might add some code to complain if
lock files exist, rather than blundering onward.

"How Do They Do That?" I asked myself, and in the best hacking
tradition, went off to steal^H^H^H^H^H browse some code.
I found a piece that does the business in unbatch.c that had
findfirst/findnext, and THEN noticed a #define tucked far
away that turned findfirst into _dos_findfirst.  WHY?  There
seems precious little difference between these two
functions, except for parameter ordering.

I found what may be a clue in compat.h, a file that starts
with a remark about Microsoft/Borland compatibility, and
also contains this #define (although the only file that
includes compat.h is exec.c, and that file doesn't
contain any use of findfirst!).

Borland provide both findfirst AND _dos_findfirst.  Does
M'soft only offer the latter?

And Borland's help file indicates findfirst is only for
dos and windows.  How does one do the equiv thing in Unix?
(No, I'm not thinking of porting prune to Unix, just
curious).
