Hello, just tried to build 5.10.0 on OpenVMS Alpha 7.3 (yes, I know it is old) with Compaq C V6.5-001.
The build fails in vms.c with he following error message: CC/DECC/NOANSI_ALIAS /Include=[]/Standard=Relaxed_ANSI/Prefix=All/Obj=.obj/NoLis t/float=ieee/ieee=denorm/Define=(PERL_CORE,_LARGEFILE=1) VMS.C case_perm = PPROP$K_CASE_BLIND; ....................^ %CC-E-UNDECLARED, In this statement, "PPROP$K_CASE_BLIND" is not declared. at line number 13603 in file DISK$USER:[ZINSER.TMP.PERL]vms.c;1 if ((case_perm == PPROP$K_CASE_SENSITIVE) || ......................^ %CC-E-UNDECLARED, In this statement, "PPROP$K_CASE_SENSITIVE" is not declared. at line number 13607 in file DISK$USER:[ZINSER.TMP.PERL]vms.c;1 According to the docset these were added to VMS in 7.3-1 so a fix might look like this in line 13597 #if defined(JPI$_CASE_LOOKUP_PERM) && !defined(__VAX) && (__CRTL_VER >= 70301000) which is really the same as already employed for the include earlier in the code.
