Then for cross plateform compatibility, we should modify all the references
to perl script to include the program name. It doesn't hurt Linux, and is
essential in a DOS shell.

I researched your 'uname' suggestion and came up with the following. It
works on my system and it should work on Linux.
Add this to makefile.common:
OSTYPE := $(shell uname)
Later, when building the executible, we can reference the correct filename,
regardless of the OS:
{makefile in dll-src directory}
ifeq ($(OSTYPE),MS-DOS)
EXT = .EXE
else
EXT =
endif
TARGET1 = dll$(EXT)
TARGET2 = makelx$(EXT)
SINGLE_SRC_TARGETS = genlds$(EXT) fixdeps$(EXT)
I still can't write to sourceforge (I'm sure it's a problem in my
configuration), so if anyone wants to make this change and check it in, I
would appreciate it.
I think the biggest obstacle to cross system compatiblity lies in the
utility program (makelx.exe, etc). They are a major pain to build on
non-Linux systems. I will probably work on building them over the weekend
(again), but I didn't have much luck last weekend.
