Subject: libtool: mingw hangs in func_convert_core_msys_to_w32
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=37b7146c13a62a46273fd1478e6ad8fe42f9b551;p=thirdparty%2Flibtool.git

libtool: mingw hangs in func_convert_core_msys_to_w32

The `cmd //c ...` is is an invocation of the Windows console command
line shell `cmd`. The slashes are Windows console shell command line
option switch characters '/', with `cmd /c ...` meant to be
equivalent to `sh -c ...`.

It results in the Windows `cmd` shell being invoked as an interactive
console shell, as if invoked with the '/k' switch, but ignoring any
provided command string, hanging builds!

* build-aux/ltmain.in: Remove additional forward slash for option.
