As I didn't know very much on the state of EGCS for Windows using MINGW32
(no cygwin), I decided to have a try on building it.
First impressions: it actually configures and builds now! Congratulations!
There were a few minor glitches, which I will report below.
I also included fixes. Hopefully they will be useful for someone, they
are mainly to illustrate what I had to change. Please correct them and
include them in the main sources if possible.
I used bash as shell for configuring/building.
The configure command was:
./configure --target=i586-pc-mingw32 --host=i586-pc-mingw32
Here are the problems I encountered:
1) Because of errors related to missing definitions of O_RDWR (and similar),
ULONG_MAX and offsetof, I added the following includes to xm-mingw32.h:
#include <stdlib.h>
#include <stddef.h>
#include <limits.h>
#include <fcntl.h>
This fixed the problems, although I don't know if this is the proper fix
or not.
2) For compiling the f77 directory, I had to use HOST_CC=gcc
This was mentioned in the Makefile.
3) For installing the tar options had to be changed in the main Makefile
as follows: (I don't know how I should configure this)

--- gcc/Makefile.in Tue Nov 17 22:02:54 1998

# Options for tar when copying trees. So HPUX can override it.
! TAROUTOPTS = xpBf
# Select which version of fixincludes to use (I.E. regular versus SVR4)
# This value is overridden directly by configure.

# Options for tar when copying trees. So HPUX can override it.
! TAROUTOPTS = xmpBf
# Select which version of fixincludes to use (I.E. regular versus SVR4)
# This value is overridden directly by configure.
4) For installing, the f77 language fragment had to be changed
to add $(exeext)'s as follows:

5) makeinfo build fails
The seems to be some include-file mess with missing definitions
and multiple definitions. As I'm not interested in info files for
the moment, I tried just to install gcc without info, but for some
reason that is hard. All language front-ends got installed but gcc.exe
and cc1.exe and cpp.exe where not installed :-(
As a work-around I modified the install-normal target to do install-info
last. Maybe it would be a good idea to do documentation last anyway.
6) chill didn't get compiled properly
This was also a $(exeext) problem, here is a patch:

I didn't do any testing runs, but if it is straightforward to configure I'll
certainly look into that. (If somebody wants to give me a hint, I'd welcome
that though I didn't read the fine manuals yet.)

Geert
