dnl As of autoconf 2.53, the standard largefile test fails for Linux/gcc.
dnl It does not put the largefiles arguments into CFLAGS, even though Linux/gcc
dnl does need them. Since wxWidgets had already solved this exact problem,
dnl Bryce asked Vadim Zeitlin of the wxWidgets project if Bochs could grab
dnl their largefile test, and he said it was fine. The re-implemented
dnl AC_SYS_LARGEFILE test can be found in aclocal.m4.
AC_SYS_LARGEFILE
dnl This logic came from wxWidgets as well. Bryce added the CFLAGS and
dnl CXXFLAGS lines, since Bochs makefiles don't use CPPFLAGS at all.
dnl
dnl we need to define _FILE_OFFSET_BITS or _LARGE_FILES on the compiler command
dnl line because otherwise the system headers risk being included before
dnl config.h which defines these constants leading to inconsistent
dnl sizeof(off_t) in different source files of the same program and linking

dnl Add the -lm library if math functions cannot be used without it.
dnl This check is important on cygwin because of the bizarre way that they
dnl have organized functions into libraries. On cygwin, both libc.a and
dnl libm.a are symbolic links to a single lib libcygwin.a. This means that
dnl 1) linking with -lm is not necessary, and
dnl 2) linking with -lm is dangerous if the order of libraries is wrong
dnl In particular, if you compile any program with -mno-cygwin and link with
dnl -lm, it will crash instantly when it is run. This happens because the
dnl linker incorrectly links the Cygwin libm.a (==libcygwin.a), which replaces
dnl the ___main function instead of allowing it to be defined by
dnl /usr/lib/mingw/libmingw32.a as it should be.
dnl
dnl On MacOS X, this test will find that -lm is unnecessary and leave it out.
dnl
dnl Just check a few math functions. If they are all found without
dnl -lm, then we must not need -lm.
