[m-dev.] Errors compiling Mercury ROTD using Cygwin

[Martin McDonough]

I've run into an error compiling Mercury (most recent ROTD) using Cygwin
(64-bit) on Windows 7 64-bit.


https://gist.github.com/FlyingJester/66643007fb8f6d46b00a

The main error seems to be when linking:
top_level_init.o:top_level_init.c:(.rdata$.refptr._bss_start__[.refptr._bss_start__]+0x0):
undefined reference to `_bss_start__'
top_level_init.o:top_level_init.c:(.rdata$.refptr._data_start__[.refptr._data_start__]+0x0):
undefined reference to `_data_start__'
top_level_init.o:top_level_init.c:(.rdata$.refptr._bss_end__[.refptr._bss_end__]+0x0):
undefined reference to `_bss_end__'
top_level_init.o:top_level_init.c:(.rdata$.refptr._data_end__[.refptr._data_end__]+0x0):
undefined reference to `_data_end__'



A quick web search suggests this may mean a bad/mismatched linker script,
although I have no idea if that is applicable here.

Any help would be greatly appreciated!

Running './configure' is not portable; you need to run 'sh configure'.
That makes a difference on Cygwin.

See README.Cygwin and the INSTALL file.

I get the same result using `sh configure` instead.

A similar issue appears to be occurring with the MinGW64 GCC 4.9. I've
added an entry to the bug database for this one
(https://www.mercurylang.org/bugs/view.php?id=398).

Further updates will be posted there.
