Subject: bash command line limit

There is any expected specific limit to command line length in
bash scripts on cygwin ?

Testing octave, I am noticing that line longer than ~ 5000 characters
are aborted with no message.

The line is :
--------------------------------------------------------------------
OCTAVE_BINDIR="$builddir/src" \
OCTAVE_SITE_INITFILE="$top_srcdir/scripts/startup/main-rcfile" \
OCTAVE_DEFAULT_QT_SETTINGS="$builddir/libgui/default-qt-settings" \
OCTAVE_LOCALE_DIR="$builddir/libgui/languages" \
OCTAVE_JAVA_DIR="$builddir/scripts/java" \
   exec $builddir/libtool -v --mode=execute $driver \
     "$octave_executable" --no-init-path --path="$LOADPATH" \
     --image-path="$IMAGEPATH" --doc-cache-file="$DOCFILE" \
     --built-in-docstrings-file="$BUILT_IN_DOCSTRINGS_FILE" \
     --texi-macros-file="$TEXIMACROSFILE" --info-file="$INFOFILE" "$@"
---------------------------------------------------------------------
end its full lenght when expended is over 5000 characters.

Just removing the last "\" before exec and dropping the length ~ 4950
and the script works again


In theory , the limit should be much more:

$ getconf ARG_MAX
32000

Regards
Marco
