Thanks. I can confirm the fix for HP-UX. Looks like I missed another
platform where this is a problem, IRIX. Using the same gnulib-tool
invocation as on HP-UX:
$ ./gnulib-tool --create-testdir --dir=t arpa_inet crypto/md5 \
environ filemode fnmatch fnmatch-gnu getdate gettext glob human \
iconv_open inet_pton lstat mbswidth memmem mktime modechange poll \
regex socklen strcase strftime strptime strtok_r vsnprintf \
vsnprintf-posix wcwidth
$ cd t
$ ./configure
$ gmake
...
cc -DHAVE_CONFIG_H -I. -I.. -I../intl -g -c -o getdate.o getdate.c

How about adding something like "|| (defined __sgi && defined
_GL_JUST_INCLUDE_SYSTEM_WCHAR_H)" to your patch?
