32 build Wget on the Windows platform using its "native" API,
33 sometimes referred to as "Win32". (This excludes Cygwin, which
34 defines a Unix-compatible layer and is handled with configure.)
36 The above "information about compilers" includes both actual
37 differences in compilers (such as how to construct 64-bit constants
38 or whether C99 `bool' is available) and the properties of the
39 compilation environment and run-time library shipped with the
40 compiler (such as whether stat handles large files or whether
43 The file is divided into sections for each compiler/environment.
44 Being based on free software, MinGW's section comes first and
45 contains most of the explanatory comments. Things that apply to
46 *all* compilers, as well as things that are specific to Wget,
47 belong in src/mswindows.h. */
