Changes between ecm-6.2.3 and ecm-6.3:
* New assembly code for 64-bit PowerPC (thanks to Philip McLaughlin)
* Allow several processes to write to the same -save file
* More routines in new P+-1 stage 2 use multi-threading in OpenMP build
* Fixed incompatibility with GMP 5.0.0
* Fixed several bugs, and now check return value from malloc() calls
* Fixed linking of GMP which prevented successful builds under Darwin

* Allow use of x86_64 asm code under MinGW
Changes between ecm-6.2.2 and ecm-6.2.3:
* Fixed incompatibility with GMP 4.3.0 when testing version in configure
* SSE2 asm code for Visual C added in stage 2 NTT code
* Small improvement to x86_64 mulredc asm code, slight speedup on Core 2
* Fixed incorrect carry propagation in subquadratic REDC code which
could lead to incorrect arithmetic in rare cases
* Fixed memory leak with -v parameter when factor was found in ECM stage 1
* Fixed bug which caused only one ECM curve to be run in spite of -c
parameter if input line did not end in newline
* Assembler mulredc code enabled by default on x86_64
Changes between ecm-6.2.1 and ecm-6.2.2:
* Updated build project files for Visual C by Brian Gladman, also adds
missing NTT_GFP_TWIDDLE_DI[FT]_BREAKOVER defines in VC parameter file
* Fixed uninitialised parameter to P-1 probability computation
* In tune.c : fixed generation of NTT_GFP_TWIDDLE_DI[FT]_BREAKOVER values,
avoid calling cputime() excessively often when timing short functions,
fixed access to uninitialised memory
* Fixed serious split infinitive in configure script (thanks Paul Leyland)
* Removed unnecessary carry propagation in x86_64 mulredc code, slight
speedup (thanks Philip McLaughlin)

'''New spkg:'''

'''md5sum:''' `a19f3d4d0e9881abe076d8a9c0ea7e7f ecm-6.3.p2.spkg`
[[BR]]
Apply [attachment:trac_5847-module_list-fix_execstack-sagelib-
rebased_to_4.7.1.alpha4.patch] '''to the Sage library'''.
(Should be applied ''after'' installing the new spkg.)
'''Note that this patch is only required (i.e., mandatory) on some Fedora
and potentially other SELinux-enabled systems''', and apparently only in
conjunction with more recent versions of GCC (>= 4.6).
I.e., you should be able to use the new GMP-ECM spkg on other systems
without installing any patches or other spkgs.

Comment(by leif):
Had to fix some old changelog entry.
Corrected spkg at new location.
