You might be able to save yourself some typing by using a typedef in a complex.h file that you create and thereby avoid having to modify the original source at all.

Hi Tony.
That's good news - I couldn't find much info on the nuts and bolts of the
complex stuff in gcc-3.4.x (Is there some manual that is up-to-date? The
gcc manuals I found are from 2002 or older).
I just tried to change a few complex declarations to _Complex on the big
machine and they even seem compatible with the normal 'complex'
declarations.
The program doesn't use sophisticated complex functions, so there's a
good possibility it'll work.
Anyway, I'll also explore the minGW way, as I would appreciate
stand-alone executables.
Thanks for the info.
John

Sorry, there's nothing obviously wrong that I can see. But if this truly was working a week ago and you didn't change your Cygwin installation at all (configuration or otherwise) during that time, I would suggest looking at things that changed external to Cygwin. For instance, have you performed any Windows updates? Fiddled with or installed any firewall or anti-virus software? FWIW, your 'cygcheck' results show that 'exim' is not running. This is consistent with your claim that the results you're seeing are causing 'exim' to fail to start. Perhaps it would also be worthwhile to detail your installation and configuration steps for 'exim' and the message that you get when you attempt to start it with 'cygrunsrv'. -- Larry Hall http://www.rfk.com RFK Partners, Inc.

Well gcc 3.4.4 has built-in support for complex types, i.e. the following works
(without including complex.h)
_Complex double x = 7 + 8i;
x += -3 - 4i;
x *= 2 + 5i;
x /= 3 - 4i;
printf("(%f,%f)\n", creal(x), cimag(x));
but it does not have built-in support for all of the complex functions
that are declared in complex.h. I would assume the "problem" is
more of newlib issue than a gcc one.

Complex.h file
Hi guys & gals. I'm tying to port a program of mine to cygwin, and have the following problem: complex.h is not found. A search in the cygwin tree reveals: /usr/lib/i686-pc-mingw32/3.4.4/include/c++/backward/complex.h /usr/lib/i686-pc-cygwin/3.4.4/include/c++/backward/complex.h /usr/include/mingw/complex.h But, as I use gcc, and normal c (not c++), I suspect none of these are seen. On my Linux machine, all compiles well (same gcc version). The compiler complains about the missing complex.h and about the complex type in a file, even though I read gcc has complex C-99 support built-in since 3.4.1 Can someone help here?
