[I am new to this list, so excuse me if the subject has already been
beaten to death...]

Dear DJGPP-users,
after installing the recent version (1.12) I encountered a problem
with using 'complex' class in libgpp.

A program, which compiles under Linux gcc, TurboC++ and one-year-
older version of DJGPP, doesn't want to compile with new DJGPP.

First, it reported "class under-defined" or alike at compile time.
Tracing the problem, I found out that file "complex.h" was
UNIX-type, i.e. it #included "Complex.h", which is obviously useless
under DOS. OK, a solution was to copy "complex.h" from older DJGPP,
which correctly included "_complex.h" [if this bug has not been
revealed yet, consider the message as bug report].

After this, compiler got satisfied, but now linker generates errors
that all functions defined in "_complex.h" are not referenced. I
checked, that libgpp is being found and used (omitting -lgpp produces
errors about stream functions not being found). Browsing libgpp.a it
is possible to find a lot of "...Complex..." references, i.e. Complex
has been compiled into libgpp.a.

Now I am totally confused. The only explanation I see is that
libgpp.a has been built with some other absolutely incompatible
"_complex.h" (or "Complex.h", or whatever) and needs to be rebuilt,
but current "_complex.h" is bit-to- bit identical with the one from
the older release.


Ideas, suggestions, hints?
