On my system (Win98SE) using Win95Cmd I get (with Cygwin gawk-3.1.1-3):
C:\WINDOWS>\cygwin\bin\gawk "BEGIN {print \"hi\"}; END {print \"bye\"}"
<\autoexec.bat
hi
gawk: cmd. line:1: fatal: file `-' is a directory
C:\WINDOWS>
OTOH:
C:\WINDOWS>\cygwin\bin\gawk "BEGIN {print \"hi\"};END {print \"bye\"}"
\autoexec.bat
hi
bye
C:\WINDOWS>
works fine.
I don't get this problem if I run the GNUWin32 port of gawk-3.1.0-2 or
the DJGPP version of gawk-3.1.1 at a Win95Cmd command line. So it looks
like there's problem with the Cygwin port running under command.com or
win95cmd somewhere. I suppose it isn't something to do with the cygwin
dlls not being in the path? Although I'd expect some missing dll
messages if that were the case.
