It would be a good idea if we could build Mozilla directly using The Cygwin
native GCC, not using MingW.

Reproducible: Always

You should elaborate on what that means.  Do you mean building using cygwin gcc
(which used to work) or building against the cygwin runtime environment instead
of the default win32 runtime environment?  

I don't see the point in running against the cygwin runtime environment. IIRC,
you cannot access the win32 API from the cygwin environment so you'd have to
build an X11 version of mozilla on win32.  What's the point?

cls: he means that he should be able to use the included compilers in cygwin,
and not have to install mingw.

Comment 4

[Clarence Risher]

quick fix, until the actual problem with cygwin not finding the header is resolved:

In dbm/include/mcom_db.h on line 87 replace <sys/cdefs.h> with
</usr/include/sys/cdefs.h>

dmose: "not have to install mingw"?  Would that be the cygwin mingw-addon
packages or the standalone mingw packages?  Unless this bug is about building
against the cygwin runtime, mingw, in one form or another, is required.  Hrm,
HAVE_SYS_CDEFS_H should never be defined for the msvcrt runtime builds so I
guess this *is* about building against the cygwin runtime.

Comment 6

[Mike Shaver (:shaver emeritus)]

The problem with mingw not finding the header is that mingw doesn't _have_ that
header.

I'm sort of hoping we solve this (and the related sys/byteorder.h problem) by
ripping mcom_db.h out by the roots, but that's just me.
