Installation of mtools on the usual platforms is now pretty straightforward:
1. Run ./configure
2. Run make
Configuration options:
* Use ./configure --enable-vold to compile mtools to use Solaris'
vold instead of directly accessing the floppy disk
* Use ./configure --disable-xdf to disable support for Xdf disks on Linux
* Use ./configure --enable-new-vold to compile mtools to use the *new*
vold for Solaris. With this, you no longer need precmd=volcheck, and
users don't need to type "eject" before pushing the button.
Further doc can be found in the manpages, and in the texinfo doc. The
texinfo doc contains the same info as the manpages, but is more up to
date. To generate a printable doc, make dvi. To generate an info file,
make info.

Compiling on BEBOX (BeOS DR9)
See detailed instructions in README.BEBOX
==================================================================
Compiling using diet libc
./configure CC="diet gcc -nostdinc" ac_cv_build=x86_64-pc-linux-dietlibc ac_cv_header_iconv_h=no
make
# Diet libc is not properly supported by autoconf's config.sub hence
# the manual setting of ac_cv_build=
# Diet libc does have iconv support, but unfortunately its iconv_open
# supports no encoding that represents wchar_t. UCS-4 is supported,
# but not UCS-4LE which would be needed on Intel processor on Linux.
# N.B. Dietlibc programs are always statically linked, and thus
# actually *larger* than a program compiled against the system libc,
# which is usually dynamically linked. Thus dietlibc only makes sense
# in a situation where dynamic linking is not possible or desirable
# (embedded systems), or for portability testing.
==================================================================
Cross-compiling for windows, 32 bit using mingw
./configure --host=i686-w64-mingw32
make
==================================================================
Cross-compiling for windows, "64" bit using mingw
./configure --host=x86_64-w64-mingw32
make
==================================================================
Open Watcom compiler
Minimal build (with correct open watcom env of INCLUDE, PATH, etc,
assuming sh, gnu make, etc. E.g. cygwin/msys2/w64devkit on windows):
./configure --host=i386-pc-mingw32 CC="owcc -bnt -fo=.o"
make
CC option -bnt seems to targets win95+ (runs on win10), and -fo=.o
creates .o objects (which the makefile expects) instead of .obj .
The default CFLAGS seems to be "-g".
I believe configure can/does detect .exe/.obj as EXEEXT and OBJEXT,
but I don't think Makefile uses them, hence the "manual" handling
(it's probably not worth "fixing" Makefile.in just for this).
To strip, use (ow) "wstrip" - one file at a time, or add "-s" to CC.
However, it seems that stripping (both methods) is unable to fully
revert the effect of "-g", so for the smallest binaries, override -g
by adding CFLAGS=... (empty works, or -Os, etc).
CFLAGS=-O2 currently results in this crashing: mcopy -ix.img file ::
(wasn't explored further).
==================================================================
Cross-Compiling for UnixPC
./configure CC=/usr/local/bin/unixpc-gcc CFLAGS="-shlib -O3 -Os -fomit-frame-pointer" --host unixpc
make
==================================================================
Clang, all warnings except rare warnings that are "over the top"
./configure CC=clang CFLAGS="-Weverything -Wno-padded -Wno-disabled-macro-expansion" --prefix=""
make
# For over-the-top warnings, see:
# disabled-macro-expansion:
# https://stackoverflow.com/questions/34704422/warning-disabled-expansion-of-recursive-macro
# padded:
# https://stackoverflow.com/questions/40662265/warning-for-struct-padding-in-clang
# padding warning is also shown when padding happens at end of
# structure, i.e. not easily avoidable by just re-ordering the variables
==================================================================
Gcc, "all" warnings
./configure CC=gcc CFLAGS="-pedantic -Wall -Wextra -Wcast-qual -Wunused-macros -Wshadow -Wwrite-strings -Wundef -Wstrict-prototypes -Wunused -Wmissing-prototypes -Wmissing-declarations -Wdeclaration-after-statement -Wunused-but-set-variable"
