#define NOVELL_BUG_FAILSAFE
/* The optional "long filename" support available with some MSDOS compiler
* environment running under VFAT systems (Win95) is controlled with the
* help of the two preprocessor symbols USE_VFAT and USE_LFN:
* - USE_VFAT is a compile time switch that selects the long filename
* semantics in mapname()
* - USE_LFN is a macro equating to a boolean expression indicating
* whether long filenames are supported. If available, this
* macro should make use of a runtime function checking the
* LFN support.
*
* The code in msdos.c distinguishes three cases:
* 1.) USE_VFAT is not defined:
* No support of LFN is included; filenames are mapped to 8+3 plain FAT
* syntax unconditionally.
* This is achieved by ``#define MAYBE_PLAIN_FAT'' to include the plain
* FAT name mapping code and by ``#undef USE_LFN'' to disable bypassing
* of the FAT mapping at runtime.
* 2.) USE_VFAT is defined:
* Support for LFN is enabled.
* a) USE_LFN is undefined:
* There is no (runtime) check available to distinguish between OS
* environments that support VFAT extensions and those that do not.
* In this case, filenames are mapped to the more liberal VFAT LFN
* syntax unconditionally. The internal switch MAYBE_PLAIN_FAT remains
* undefined to exclude to "map to plain FAT" code parts.
* b) USE_LFN is defined (hopefully to a boolean runtime LFN check function):
* "#define MAYBE_PLAIN_FAT" is applied to include the plain FAT mapping
* code; the programs checks at runtime whether the OS supports LFN and
* uses the appropiate mapping syntax.
*/
/* Some environments, like DJGPP v2, can support long filenames on VFAT
* systems and DOS 8.3 filenames on FAT systems in the same executable. If
* such support is available, USE_LFN should be defined to an expression
* that will return non-zero when long filenames API should be used, zero
* otherwise.
