How to repeat:
$ ./configure; make

Currently we don't have support for that compiler.

Hey, it's standard GCC. What's not supported about that compiler?

Cygwin != Windows

The cygwin fix breaks our Novell build, so we had to revert it for now ...

The problem still exists in v5.0.15.

Cygwin is using linux-like GCC - not M$-VisualStudio.

Please consider the following-

#ifdef __CYGWIN__
    // do Cygwin fix
#else
    // Novel
#endif

thnx

The make tries this-
gcc -O3 -DDBUG_OFF       comp_err.c   -o comp_err

this command lacks the -I flag for all the include directories.
So it is probably something in the `configure` and not in the c file itself.

it is actually an automake issue, see

  http://lists.mysql.com/internals/30580

so there is no way to work around it using compiler/preprocessor magic

For what it's worth, I corrected this by altering the Makefile in the ./extra folder.

At line 885 (in my file), the dependency is incomplete which is why the compiler has a problem building the target.

I changed the line:
$(top_builddir)/include/mysqld_error.h: comp_err

to:
$(top_builddir)/include/mysqld_error.h: comp_err$(EXEEXT)

and it now builds fine, on Cygwin and FC4.

Ignore my previous post, I neglected to check the "Changeset".
