Let MPIR build without C++ support on Cygwin

[jpflori]

GMP/MPIR used to include a hack to configure faster. This makes GMP/MPIR build badly on cygwin when C++ support is disabled and is not needed anymore anyway. See:

• ​https://sourceware.org/ml/cygwin/2013-06/msg00580.html

The spkg here backports a fix from:

• ​https://github.com/wbhart/mpir/commit/2320c7d965e3277fddaf2390fdf7032d34954c8c

Use git branch.

Spkg diff, for review only.

[jdemeyer]

configure.in should be patched before configure (i.e. reorder the patches in the patch file).

[jpflori]

Fixed (in the spkg, no new diff).

Replying to jdemeyer:

configure.in should be patched before configure (i.e. reorder the patches in the patch file).

I'd even say configure must be patched after an autoconf run...

[jpflori]

I more or less patched configure.in and ran autoconf (not autoreconf because even with Jeroen very nice spkg the diff was too large, and might even have failed if I remember correctly, GMP/MPIR autotools scripts are old and quite dirty, but also very smart for other things) to get this.

As this should only be temporary (this will be hopefully in the next MPIR release where a lot of other patches from the spkg, all of them I even think, are integrated), I also removed all superfluous changes made by autoconf (whic sometimes insists on adding a space here and there and so on).

I did not patch both files by hand.

Let MPIR build without C++ support on Cygwin.

I just tried to compile on cygwin64 with the current branch and it failed with the following:

Any ideas? Thanks.

[jpflori]

Yes, a bunch of ideas :) It's not expected to work anyway, adding support is not that hard, but was not the point of this ticket, the few steps for Cygwin64 support are:

• updated the configfsf.* scripts,
• tweak the ABI stuff in spkg-install.

I think that's all. A priori, all needed fixed are in MPIR master git branchn bt I've not tested it lately.

[tscrim]

This worked for me on Cygwin32, and I'll (try to remember to) try this on my ubuntu machine tonight.

For Cygwin64, the configfsf.* is #14648, but where is the ABI stuff I need to change documented? Thanks for walking me through this.

[tscrim]

Works for me on Ubuntu, now to see if I can get this to work on Cygwin64...

[jpflori]

Please add Cygwin64 in other tickets: basically #14648 for the configfsf.* update and potentially a different one for modifying the spkg-install script.

[tscrim]

Works on Cygwin64 with #14648 and #15651, so I'm going to stop daddling and set this to positive review. Thanks Jean-Pierre.
