Running  i586-pc-msdosdjgpp-nm on libstdc++ indicated that it was in the wrong 
format.  When I tried to compile the test program initially, it could not find 
libstdc++ .  I symlinked to the version that is invoked in standard gcc 
compiles...obviously not the correct move.  The question is, why did I not get 
a DOS version when I built the compiler?

I used the instructions from delorie.com for the build.  The only variance was 
that I used djcrx203.zip, rather than 202, which was not available.  When I 
made gcc, I got compile errors in gcc-2.1.8/objc/archive.c and misc.c.  In 
misc.c the error inidcated a conflict of types for whcar_t in stddef.h and 
stdlib.h.  I managed to get it to compile by commenting out the include of 
stdlib.h in archive.c, and changing the include of stddef.h to stdlib.h.  I 
suspect there is a version incompatibility somewhere.  Should I be using 
diffierent versions of binutils and gcc with djcrx203.zip?
