| Subject: | [PATCH] Build failure on HP-UX 11.23/64 using HP C-ANSI-C |
For multiple versions of perl built with the native compiler (HP C-ANSI-
C), I get compiler errors. Patch at the end for a fix (passes all tests)
This is perl 5, version 14, subversion 2 (v5.14.2) built for
IA64.ARCHREV_0-LP64-ld
