@subsection How do I use @samp{cygwin1.dll} with Visual Studio or MinGW?
To my knowledge, none of the Cygwin developers have done this, but we
have this report from the mailing list that it can be done this way:
If you want to load the DLL dynamically, read
@code{winsup/cygwin/how-cygtls-works.txt} and the sample code in
@code{winsup/testsuite/cygload} to understand how this works.
The short version is:
@enumerate
@item Make sure you have 4K of scratch space at the bottom of your stack.
@item Invoke @code{cygwin_dll_init()}:
@example
HMODULE h = LoadLibrary("cygwin1.dll");

<para>Since Windows uses drive letters instead of a single filesystem
root, the POSIX root <filename>/</filename> must be set to a directory
in the Windows file system using the <command>mount</command> command.
Without a <filename>/</filename> mount, Cygwin processes cannot
distinguish between the Windows CurrentDrive and SystemDrive.
<para>The <command>mount</command> command can set the POSIX root
<filename>/</filename> to any directory in the Windows file system.
In absence of such a mount, Cygwin maps <filename>/</filename> to the
root of the current Windows working directory (for example,
<filename>H:\</filename> or <filename>\\computer\share</filename>).
Normally Cygwin's <command>setup.exe</command> creates the initial
