How to specify the library name for an external function

I have an application(a shared library in C++) which uses strftime()
function of Standard C library. My application is loaded in Iplanet web
server as a plugin. As strftime() function is also defined by one of the
Iplanet web server libraries, So the strftime() call from my application
is getting its definition from web server library rather than standard C
library.

In a shared environment where the same function is defined by two
libraries (e.g. in my case Standard C library and Iplanet Server
library), How can I specify my application to a pick the definition from
a particular library at run-time ??

I did a Windows 'Search' of the MinGW '.a' files for the strings 
'_cputs' and '_cscanf'. Both searches turned up the following 7 files:
libcrtdll.a, libmsvcr70.a, libmsvcr70d.a, libmsvcr71.a, libmsvcr71d.a, 
libmsvcrt.a, and libmsvcrtd.a.

I don't know just which of those you link to ... or if it matters ... or

if it's even definite that it has to be one of those files.
I'd opt for -lmsvcrt but there's no guarantee that's correct :-)

Try a MinGW-specific list if you don't get a satisfactory answer here.

Hth.

Cheers,
Rob
