post-install script failed, if PROXY_HOST set

[makon2]

if PROXY_HOST set, the generated post-install.sh failed with error:
\cygwin\post-install.sh: line 5: syntax error near unexpected token `then'
The failure is the ";" in line 5 with echo: the ";" terminate the command and then the "then" is unexpected.
Is "then" allone in the next line, then it works:
echo if [[ $HOSTNAME == "%COMPUTERNAME%" ]]
echo then
You can try in a interactiv shell: echo message; then it display the same error.
With kind regards
