Looking at 'latexmk.pl' script, I see the block:

elsif ( $^O eq "cygwin" ) {
[...]
# For both fptex and miktex, the following makes error messages explicit:
$latex_silent_switch  = '-interaction=batchmode -c-style-errors';
$pdflatex_silent_switch  = '-interaction=batchmode -c-style-errors';
[...]
}
  else {

so, if I read correctly, on Cygwin TL is confused with fptex or 
miktex... Really I do not see any reason for that block on current 
Cygwin-1.7...

Indeed omitting it *completely*,

-elsif ( $^O eq "cygwin" ) {
-[...]
-# For both fptex and miktex, the following makes error messages -explicit:
-$latex_silent_switch  = '-interaction=batchmode -c-style-errors';
-$pdflatex_silent_switch  = '-interaction=batchmode -c-style-errors';
-[...]
-}
  else {

the script works just fine :-)

Ken, what do you think?

Ciao,
Angelo.
