Using gcc v2.6.3 and ld v2.5.2 (with BFD 2.5) I get undefined reference
errors of the listed internal symbols as in...

D:\USERS\FREDI\MCSIM>make

'Linking mcsim...'

All four of these symbols are listed in my libc.a which is explicitely
included in the link as shown above.  I know that these are referenced
in the default link script \usr\lib\djgpp.lnk, but I don't really
understand what that is about.

Can anyone direct me to the simplest solution?  I don't think I
should have to muck with anything and I'm sure that some environment
variable is not set or something.
