436# This macro is invoked by any PROG_compiler macro to establish the
437# --enable-doscompile option, used when one wants to compile an executable
438# under Cygwin which also runs directly under DOS (without requiring
439# Cygwin1.dll). The job of this macro is to make sure the option is correct and
440# to set enable_doscompile. Legal values are mingw, msvc, and no (disabled).
441# mingw: Fake mingw under cygwin, using GCC tools and -mno-cygwin. The most
442#        important thing here is that preprocess, compile, and link steps
443#        *all* see -mno-cygwin.
444# msvc:  Assume the presence of cl/link. It's the user's responsibility to
445#        make sure their PATH is correct. In particular, that MSVC link is
446#        found and not cygwin link (we want to do code linking, not file
447#        linking).
448# It's the responsibility of individual PROG_compiler macros to ensure that
449# they correctly set the compiler search list and preprocess, compile, and
450# link flags. This is tied to compiler setup because in practice invocations
451# of the preprocessor and linker are made through the compiler.

1845# libraries need to point to 64-bit subdirectories. If they do not already do
1846# that, fix them. This patch is evolving, as are GCC compilers.  GCC 4.2.1

1850# Both SPARC and x86 have this issue, but a different hardware id string is

1852# the string. This will fail, of course, if we're cross-compiling. The
1853# alternative is to fail on a regular basis each time a new CPU identifier is
1854# needed. This macro will also fail if the search list reported with
1855# -print-search-dirs differs between the C, C++, and Fortran compilers; each
1856# have their own setting in libtool.  If GCC reports the correct search list
1857# given the -m64 flag, the best solution is to define CC='gcc -m64', and

2487# directories, hence both the include directory and link flags must be
2488# specified. There are two mandatory arguments and two optional arguments.
2489#
2490# The first argument (mandatory) should be a name (LibraryName) for the
2491# library.  The second argument (mandatory) should be an abbreviation in
2492# upper case letters (LBRY) for the library. Ultimately, the macro will
2493# specify two variables, LBRYINCDIR and LBRYLIB, to be substituted in files
2494# generated during configuration; a preprocessor symbol COIN_HAS_LBRY; and a
2495# matching automake conditional COIN_HAS_LBRY. LBRYINCDIR should specify the
2496# directory containing include files for the library. LBRYLIB should specify
2497# the flags necessary to link to the library. A variable coin_has_lbry will
2498# be set to true or false, as appropriate. A variable lbry_libcheck will be
2499# be set to yes or no; no indicates link checks should not be attempted.
2500#
2501# The macro defines three configure arguments, --with-libraryname-incdir,
2502# --with-libraryname-lib, and --disable-libraryname-libcheck, by converting
2503# LibraryName to lower case.
2504#
2505# LBRYINCDIR and LBRYLIB can be specified as environment variables or as
2506# part of the configure command using --with-libraryname-incdir and
2507# --with-libraryname-lib, respectively. Command line arguments override
2508# environment variables.
2509#
2510# If a third argument is given, it should specify a file in LBRYINCDIR.  The
2511# macro will check for the presence of the file. If a fourth argument is given,
2512# it should specify a function name, `fname'.  The macro will attempt to link a
2513# trivial program containing a parameterless call to the function, `fname()',
2514# using the LBRYLIB flags. The link check uses C as the language; this has been
2515# adequate to date but has limitations. It is possible to disable the link
2516# check by specifying --disable-libraryname-libcheck. This is a workaround for
2517# instances where the link check does not work properly, for whatever reason.
2518# If you're trying to link to a Fortran library, consider using F77_FUNC or
2519# FC_FUNC to obtain a mangled fname appropriate for use from C code. For a C++
