@ -161,6 +161,19 @@ This is not to be confused with 'MinGW' (Minimalist GNU for Windows),
which is a completely separate effort. That project's home page is
@file{http://www.mingw.org/index.shtml}.
@subsection Can I build a Cygwin program that does not require cygwin1.dll at runtime?
No. If your program uses the Cygwin API, then your executable cannot
run without cygwin1.dll. In particular, it is not possible to
statically link with a Cygwin library to obtain an independent,
self-contained executable.
If this is an issue because you intend to distribute your Cygwin
application, then you had better read and understand
@file{http://cygwin.com/licensing.html}, which explains the licensing
options. Unless you purchase a special commercial license from
Red Hat, then your Cygwin application must conform to the GPL.
@subsection Can I link with both MSVCRT*.DLL and cygwin1.dll?
No, you must use one or the other, they are mutually exclusive.
