I own an amd64 system, so I thought I'd offer Bill a completed build.

I followed three steps above, and the result was:

address@hidden code]$ git clone git://git.savannah.nongnu.org/nmh.git

build log is in build_nmh.log

Further unwinding of the problem is that on my amd64 (Mageia 3) system,
size_t winds up being resolved as an 'unsigned long int' in the gcc 4.7.2
headers (/path/to/gcc/4.7.2/include/stddef.h).  The line in question is:

>         for ( i = 0; i < _yybytes_len; ++i )

where 'i' is an int, and _yybytes_len is size_t.  Since timep.c is generated 
by flex, so changing the _yy* variables isn't an easy out.  We could add

typedef long int yy_size_t

to the dtimep.l source, but I'm concerned about the extern linkage in the
generated dtimep.c file immediately after (starting on line 156 of the file):

typedef size_t yy_size_t;

extern yy_size_t yyleng;


It is now 27yrs since I was introduced to MH and have been using it ever 
since.  First code I rehost on each OS as I have moved from AIX 2.2.1 ->
AIX 3.x, AIX 4.1 -> SCO Openserver 5 -> Unixware 7 -> Linux.  [there was
a failed attempt at QNX, but that's another story]

Love the code, wish to contribute more.
