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