Search the disk for them.  From what I know, they are there, just not on 
the PATH.  I think they should be in some subdirectory of WINDOWS.

Please investigate more.  This shouldn't be happening in v1.x.  v2.0 (or 
rather the gcc 2.7.2 compiler which came with v2.0) had such problems in 
C++ programs because it didn't pack structs, but I don't think this was 
ever reported in v1.x.

Call `_get_dos_version' and test if it returns 7.0 or higher.  Windows 95 
identifies itself as DOS 7.0.

DJGPP v1.x doesn't support long filenames, if that's what you mean.  You 
need DJGPP v2.01 for this to work.  The long filename API uses different 
DOS functions for file-oriented operations, so all of the low-level libc 
functions which deal with filenames need to be rewritten.
