long double: from mac to windows..

Hi all, I hope I can do a question about C programming in this forum; otherwise I apologize. I implemented a C program using my mac book. Now, my client wants to migrate to windows OS (MinGW). Program does many calculation using long double: on mac it works fine, otherwise on winz doesn't. I read on internet the problem is that long double type is supposed to be a double type in WinZ, because it is no supported. Making sizeof of double and long double, I obtain: MAC DOUBLE=8, LONG DOUBLE=16 WINZ DOUBLE=8, LONG DOUBLE=12 Is there a solution or a workaround? How can I "force" the use of long double or its simulation? Sorry for my English. Thanks in advance | |

| Maybe you should look at an arbitrary precision library, like GMP. It is cross-platform and compiles under windows using MSYS and MinGW as well. | |

Thank you for your answer. I investigate about GMP. How can I use that library? | |

You can find all documentation and example code on library website: http://gmplib.org/ | |
