[Buildroot] [PATCH v7] openvmtools: new package

Found it.
This is because of gcc 4.8's intended behaviour on sizeof() function in
cases when calling on a pointer.
See https://gcc.gnu.org/gcc-4.8/porting_to.html "New warnings for pointer
It also exists as an unconfirmed bug:
This behaviour is only gcc 4.8, while 4.9 and pre-4.8 versions shouldn't do
this (Sourcery uses 4.7 and 4.6, I used the own toolchain w/ 4.9)

On the open-vm-tools mail list, it came up
http://sourceforge.net/p/open-vm-tools/mailman/message/32550520/ , but they
used -Wno-sizeof-pointer-memaccess for compilation - basically silencing
the warning.

Would you recommend using -Wno-sizeof-pointer-memaccess in the .mk file or
just use a 1 line patch to syncDriverPosix.c - dereferencing
gRemoteFSTypes[i] with an asterisk?
