Autoconf-2.71 fixed handling traling white spaces (marked with an
underscore here):
AC_CHECK_FUNCS( \
strcpy \
strdup \
strchr \_
strlen \_
strcat \_
strtok \_
)
and correctly converted them to this shell code:
for ac_func in strcpy strdup strchr \ strlen \ strcat \ strtok \
do :
[...]
done
This patch removes the trailing new lines.

It's not a bug in Autotools. That were trailing spaces after the backslashes in configure.ac. The new patch fixes it. |

According to Autoconf documentation, the AC_CHECK_FUNCS supports
new lines as tokenizers.
This patch works around this issue by not escaping the new lines.
