In the past (in the Wine 1.6 era) I used an old snapshot (4.7.2) of
MinGW/MSYS on wine to build applications with success, and I would
like to stick with that snapshot for Wine Staging 2.10 since I
have found in the past later versions of MinGW/MSYS were not as reliable
as 4.7.2.

However, since that snapshot was initially installed with Wine 1.6 (or
maybe even earlier) I assume its default header locations and library locations
refer to some old wine version, and the general question is how do I override those \
to refer to the equivalent Wine Staging 2.10 locations.

I have a simple test programme (attached) that illustrates the problem:

bash.exe-3.1$ g++ /z/home/wine/wine_staging/test_rand_s.cxx
z:/home/wine/wine_staging/test_rand_s.cxx: In function 'int main()':
z:/home/wine/wine_staging/test_rand_s.cxx:18:5: error: 'errno_t' was not declared in \
this scope z:/home/wine/wine_staging/test_rand_s.cxx:18:21: error: expected ';' \
before 'err' z:/home/wine/wine_staging/test_rand_s.cxx:23:9: error: 'err' was not \
declared in this scope z:/home/wine/wine_staging/test_rand_s.cxx:23:31: error: \
'rand_s' was not declared in this scope \
z:/home/wine/wine_staging/test_rand_s.cxx:26:53: error: 'printf_s' was not declared \
in this scope z:/home/wine/wine_staging/test_rand_s.cxx:29:60: error: 'printf_s' was \
not declared in this scope z:/home/wine/wine_staging/test_rand_s.cxx:32:18: error: \
'printf_s' was not declared in this scope \
z:/home/wine/wine_staging/test_rand_s.cxx:37:9: error: 'err' was not declared in this \
scope z:/home/wine/wine_staging/test_rand_s.cxx:37:31: error: 'rand_s' was not \
declared in this scope

(I presume those errors are due to those functions not being defined
by Wine way back when).  That compile issue is solved as follows:

bash.exe-3.1$ g++ /z/home/wine/wine_staging/test_rand_s.cxx \
-I/z/opt/wine-staging/include/wine/msvcrt -I/z/opt/wine-staging/in clude/wine/windows \

final link failed: Invalid operation
collect2.exe: error: ld returned 1 exit status

However, that compile fix obviously leaves the above link issue which I attempted to \
solve by appending the options -L/z/opt/wine-staging/lib/wine -lmsvcrt
which worked (in the sense that that library was found) but apparently
that particular library does not implement rand_s and printf_s since the
same link errors occurred as above.

So what are the -l options I should be using to assure I am using the Wine
Staging 2.10 versions of the standard system libraries?

N.B. I realize this issue would likely be taken care of automatically
if I installed the latest version of MinGW/MSYS on the Wine Staging
2.10 platform.  But I have my reasons explained above why I would
prefer to use the 4.7.2 snapshot of MinGW/MSYS instead.
