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?
Thanks,
John

PS: The program I'm trying to compile is linsmith, available at
http://sf.net/projects/linsmith
