- New functions: sigsetjmp, siglongjmp.
These were only available as macros up to now, but POSIX requires that
siglongjmp has to be available as function.

What changed:
-------------
Ignore non-absolute $HOME when started from native process * uinfo.cc (cygheap_user::ontherange): Ignore $HOME if it's not starting with a slash (aka, absolute POSIX Path). Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

- When started from a non-Cygwin process, check if $HOME starts with a
slash (absolute POSIX path). Otherwise ignore it.
