# NuttX uses symbolic links to configure platform-specific directories into
|
|
# the build system. This works great except for when a Windows native
|
|
# toolchain is used in a Cygwin environment. In that case, symbolic
|
|
# links do not work correctly when accessed from the Windows native toolchain;
|
|
# rather, just look link files with the extension .lnk
|
|
#
|
|
# In this environment, the build system will work around this using this script
|
|
# as a replacement for the 'ln' command. This scrpt will simply copy the
|
|
# directory into the expected positiion.
