  Well I think this is my problem.  I don't know how to go about fixing it 
though.  Being as my application is a GUI application I NEED to include the 
windows.h file, so "BOOLEAN" will be defined as an unsigned char, however 
"boolean" is defined in one of the jpeglib includes as int.  If I went through 
all the source and changed "boolean" to "BOOLEAN" would this screw up jpeglib? 
Being as the source uses 0 for FALSE and 1 for TRUE I don't see why this 
shouldn't work.  I'll have to give it a go.

  Incidently as of right now I converted all the stdlib functions into Windows 
API functions (i.e. CreateFile instead of fopen, ReadFile instead of the 
JFREAD macro, HeapAlloc instead of malloc) and everything appears to work 
until I try to allocate a buffer with the jpeglib's memory allocation 
functions.  Then I get an invalid page fault.  This is with using the decoding 
routine from example.c.  I haven't been able to figure out the cause of this 
one.  It will do this even if I use malloc instead of HeapAlloc.  Time for 
more experimentation.

  Oh yes, and lastly, with the borland BCC32 command line compiler, jdmerge.c 
will not compile.  I get an internal backend C1107 error at line 280.  This 
seems like a bug in the borland compiler. It will compile fine if I use 
BCC32A, the alternate compiler. I have to undefine UPSAMPLE_MERGING_SUPPORTED 
so it will skip the contents of jdmerge.c to get it to compile with the 
standard WIN32 compiler.
