reduction directly. (Note, the reduction ignores integer truncation,

there is no padding occuring).
Second, when the left-hand side is truncated, multi-column characters
may get chopped in the middle. Truncated characters are not included

Fix hcversion.h generation error when using included gettext.
When configuring mutt with --enable-hcache and

BUILT_SOURCES are processed before SUBDIRS. Therefore, the

built.
The hcversion.h target runs the cpp over config.h and mutt.h,
but mutt.h includes lib.h which tries to #include <libintl.h>.
Unfortunately, libintl.h (in this configuration) is generated by the
intl subdir build and so doesn't exist yet.

This fix is somewhat of a hack but is cleaner than trying to change
automake's behavior. It inserts a '#undef ENABLE_NLS' in between the
