Programs that can use the abilities of HPFS filesystems (mixed
case, long names, extended attributes, etc.) must be explicitly
marked as such.  If the executable does not have the NEWFILES
bit of the exe header set, OS/2 will not allow the program to
access files that have filenames other than 8.3.  (The reason
for this is backwards compatibility, so that old programs don't
become confused when run on an HPFS drive.)

Since you want your program to support HPFS filenames, you must
put the following line in the .DEF file used to compile the
program (if it doesn't have one, you must create one):

	NEWFILES

Or alternatively, after the link has finished, run the EXEHDR
program on your file to set the NEWFILES bit:

	exehdr /newfiles foo.exe
