Re: Problems with installing m4 on z/OS 1.5

[Michael Elizabeth Chastain]

Hi Kevin,

The code that uses 'sys_nerr' and 'sys_errlist' is in lib/error.c.

Try adding "#include <errno.h>" to lib/error.c.
Also check "man perror" to see if 'sys_nerr' and 'sys_errlist'
are available on your system.

'sys_nerr' and 'sys_errlist' are not in Single Unix Spec version 3,
so m4 has a problem with them, not your operating system.

You could also add an unconditional '#include <string.h>' to
lib/error.c and rip out the 'HAVE_STRERROR' test.  Try to force
m4 to use the library version of strerror and not its own
private_strerror.
