Hi

The following mini program also demonstrates that it comes from
the cygwin dll.
-- slashtest.c --
#include <stdio.h>
int main(int argc, char *argv[])
{  printf("Arg1:%s:\n",argv[1]);
   return 0;
}
-- slashtest.c end --

Compile it with "gcc slashtest.c -o slashtest_cyg.exe" and
"gcc -mno-cygwin slashtest.c -o slashtest_w32.exe" and try
the following from a cmd.exe:

C:\cygwin\bin>\cygwin\home\quetschke\slashtest_w32.exe '\\\'
Arg1:'\\\':
_nothing done for a native binary, the quotes stay_

C:\cygwin\bin>\cygwin\home\quetschke\slashtest_cyg.exe '\\\'
Arg1:\':
_Hmm, one \ escaped and one ' escaped, quotes vanish if not
escaped._

C:\cygwin\bin>\cygwin\home\quetschke\slashtest_cyg.exe \\\
Arg1:\\\:
_Nothing special for a non-quoted string._

What is the deeper plan for this functionality?

Volker
