Hi Ruslan,
Sorry for the late reply.
Thanks for pointing out the problem, I havenot thought of the questions before, and I found that this patch might also cause problems on other platforms... However, here https://github.com/wine-compholio/wine-staging/tree/master/patches/msvcrt-Math_Precision is a patch created by Sebastian and it should work if your environment supports coshl/sinhl.
Thank you again and wish you a good day! :)
Regards, Zheng

Hi,
Are you sure this will be of any use if one selects SSE instead of x87 instruction set to handle doubles (like -mfpmath=sse)? No one guarantees the functions like sinh will be evaluated on x87 FPU and even that this legacy instruction set will used at all.
Regards, Ruslan

The default fpu_cw = 0x27f makes the exp/pow/cosh/sinh functions

less accurate results. This patch temporally changes fpu_cw to 0x37f in these functions for more accurate results.
Thanks to Qian for his ideas.
This patch fixes parts of these two bugs: 37149, 37150
