Re: Mangling of '\\' by cygwin dll


Hi
I run into a strange problem while using sed from a cmd.exe shell.

The problem is not sed specific and the following lines demonstrate
it with /bin/echo.

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?
