Sorry, posted this twice by accident - didn't realise it was being
moderated.
Here's the answer from the other post (from David Turner):
Known issue, "cygpath -m" is called for each source file before the
build
begins, and this is super slow on Cygwin.
This is a temporary problem until we get rid of Cygwin in the NDK (in
a
future NDK release, and hopefully the next one).
If this is a big problem, consider replacing the definition for host-
path in
build/core/definitions.mk with something like:
host-path = $(patsubst /cygdrive/c/%,c:/%,\
$(patsubst /cygdrive/d/%,d:/%, \
$1))
This assumes you're using the default cygwin drive mounting scheme,
adapt if
necessary.
