Well. Looked through source archives I had on HD and didn't find 
RHIDE_TYPED_LIBS_DJGPP.f anywhere (only RHIDE_TYPED_LIBS.f).

Also I don't see any special reason why to introduce such as there are
no related file naming conflicts even for plain DOS:

	-lg2c -lm 

is Ok for both DOS and Linux. The problem is C++ where we must have
-lstdc++ in Linux and -lstdcxx for DJGPP.

Only reason why to provide different specs for DJGPP on Linux for Fortran
libraries could be providing possibility to redefine it under both systems
when user wants to add some library which is named differently on both
systems. However even in this case this can be done without changes to
sources:

RHIDE_TYPED_LIBS.f=$(RHIDE_TYPED_LIBS_$(RHIDE_OS).f)
RHIDE_TYPED_LIBS_DJGPP.f=-lfoox -lg2c -lm
RHIDE_TYPED_LIBS_Linux.f=-lfoo+ -lg2c -lm

Should we really do that. In this case ~


Anyway I see one problem here. I didn't find sources where I have changed 
RHIDE_TYPED_LIBS.f to correct value in idespec.cc even if I remeber  
I did it sometime (perhaps change is lost sometimes). Put correct string
into idespec.cc
