c++ - initializer lists with objects is non-portable? -

-

i'm reading mozilla's c++ portability guide 1 of advice states that:

don't use initializer lists objects

non-portable example (at least, used nonportable, because hp-ux!):

subtlepoint mypoint = {300, 400};

this more of style thing @ point, why not splurge , nice constructor?

and i'm rather curious line "non-portable example (at least, used nonportable, because hp-ux!)". how come initializer lists are/were non-portable , in sense? safe use now? , term hp-ux refers to?

how come initializer lists are/were non-portable , in sense?

the guide quote implies aren't/weren't portable in sense not work in hp-ux. since using initializer list objects defined standard, implies compiler used in hp-ux not conform it. guide not specify, how breaks in hp-ux.

and term hp-ux refers to?

it operating system.

are safe use now?

if don't need support hp-ux, or other system not conform standard, , has been safe.

"at least, used be nonportable" might due mozilla no longer officially supporting new versions of products on hp-ux, or new version of compiler on hp-ux conformant. speculation.
