Comment:
tried to compile "omp_hello" as suggested "https://www.math.ucla.edu/
~wotaoyin/windows_coding.html"; compiler command: "gcc -fopenmp
omp_hello.c -o omp_hello"
Okay, thanks. I'll try to take a look at that, as and when time permits.
Nope. I still cannot reproduce the issue:
$ wget https://computing.llnl.gov/tutorials/openMP/samples/C/omp_hello.c
...
$ mingw32-gcc -fopenmp omp_hello.c -L. -o omp-hello.exe
$ mingw32-ldd omp-hello.exe
omp-hello.exe
+- libmingwex-2.dll
+- libgomp-1.dll
| +- libgcc_s_dw2-1.dll
| +- KERNEL32.dll
| +- msvcrt.dll
| +- msvcrt.dll
+- KERNEL32.dll
+- msvcrt.dll
$ ./omp-hello.exe
Hello World from thread = 0
Number of threads = 2
Hello World from thread = 1
The above is cross-compiled, on Manjaro Linux with mingw32-gcc-9.2.0, and run
under Wine-5.8. The "-L." is included in my mingw32-gcc command because I
normally link libmingwex.a statically, but I have libmingwex.dll.a in my
working directory, to link dynamically, on this occasion. I appreciate that
running under Wine may not faithfully mimic native behaviour on Windows, but it
is very unusual for Wine to successfully run code which does not run
successfully on Windows itself ... the converse is a more likely scenario.

Ticket details:
libmingwex-5.3.1 is BUGGY! it imports from self procedure
"__emutls_get_address", while not exporting it. thus any linked app would not
start. changed to --static also submitted this as review. also tested Version
5.2.2, it is good; it has not any "__emutls_get_address" inside;
