The last proposed change would break the build for mingw done under

I see where OPENSSL_SYSNAME_WIN32 is used is to define MS_STATIC.
MS_STATIC is used in 20 places in the code. Are you proposing that
MS_STATIC be changed in all 20 places for mingw, or just for the
instance in crypto/evp? Should the "static" flag be removed in all?
i am asking for OPENSSL_SYSNAME_WIN32 to be defined for MinGW targets
just the same as it is for MSVC targets; this will in effect disable
that MS_STATIC wherever it is used.
i don't know if building for old versions of Windows is even still
supported; but it appears that on at least XP, (accidentally) using
MS_STATIC can lead to spurious crashes when these static structures get
re-used and not cleaned up as they would have been if they were not static.
so a follow-up problem here may be to actually check these uses of
MS_STATIC and see if they are safe - my guess is that they have been
forgotten and they are not sane to use anymore.
The configure settings for mingw were clearly written with compiling
from cygwin in mind. Perhaps the cygwin build and the MSYS builds are
now different enough, that what you may really be asking for is a new
target for mingw built under MSYS. You could give it a name such as
"mingw-msys" or rename the old configuration to "mingw-cygwin". That
way, each could be tweaked separately.
i should have been clearer; i do compile from Cygwin. but i use the
cross-compilers provided by Cygwin under the names i686-w64-mingw32 and
x86_64-w64-mingw32 (they come from the mingw-w64 project).
the former compiles for x86, the latter for x64.
to compile for x86, i use:
./Configure mingw --cross-compile-prefix=i686-w64-mingw32-
for x64, i use:
./Configure mingw64 --cross-compile-prefix=x86_64-w64-mingw32-
but of course i remove the deprecated -mno-cygwin flag first. i'm not
sure how people are still able to use it from Cygwin; all i get if i do
a simple "./Configure mingw" then "make" is:
"gcc: The -mno-cygwin flag has been removed; use a mingw-targeted
cross-compiler."
then it errors out before even compiling the first object.
the warning makes perfect sense; compiling from Cygwin using Cygwin's
compiler is only supposed to build openssl versions linked to Cygwin's
DLLs. but here, we are cross-compiling from the Cygwin environment to an
actual Windows environment, so a cross-compiler has to be used. the
mingw-w64 ones i exposed above are the only cross-compilers currently
available by default in Cygwin.
