[Bug-tar] __attribute__() error building tar 1.27.1 on Tru64 + cc

[Daniel Richard G.]

In the course of building GNU Tar 1.27.1 on Tru64 5.1 with the vendor C
compiler, I encountered the following error:

  CC       wordsplit.o
cc: Error: /tg/freeport/src/tar/tar--1.27.1/lib/wordsplit.h, line 37: Invalid 
member declaration. (badmember)
                   __attribute__ ((__format__ (__printf__, 1, 2)));

Stop.


Apparently, the configure script neglected to check whether the compiler
supports the __attribute__() directive, as the file compiles without
error if I #define that away:

$ cc -DHAVE_CONFIG_H -I. -I/tg/freeport/src/tar/tar--1.27.1/lib -I.. 
-I/tg/freeport/src/tar/tar--1.27.1/gnu -I../ -I../gnu -std1 -warnprotos 
-readonly_strings -fast -O4 -c -o wordsplit.o 
/tg/freeport/src/tar/tar--1.27.1/lib/wordsplit.c '-D__attribute__(x)='

$ echo $?
