I found this post which seems to confirm your issue:
http://grokbase.com/t/perl/perl5-porters/1482874b1r/perl-122219-support-hexadecimal-floats#20140805amjbq5ccdqf65fqz4qxkssysf4

> In Solaris 10, strtod must be in "c99 mode" for the hexfloats to be recognized. (strtold is always in this mode). The "c99 mode' is achieved by using "c99" as the Solaris Studio compiler (driver), instead of "cc".
> In Solaris 9 (or earlier), there is no support for hexfloats. (Not blaming Solaris in particular: I'm pretty certain many older OS releases will be similarly C99-unsupportive.)
> If one is not using Solaris Studio cc (something beginning with g, maybe), one can live dangerously and explicitly link in either of /usr/lib/{32,64}/values-xpg6.o and get the "c99 strtod". Dangerous living because probably many other things get "upgraded", too.
