31 /* This file contains information about various compilers used to
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. */
