Subject: The big RosBE 1.5 compatibility patch. You will need RosBE 1.5 from this point!
X-Git-Tag: backups/jcatena-branch@60647^2~44
X-Git-Url: https://git.reactos.org/?p=reactos.git;a=commitdiff_plain;h=75538f4c0a8168a726832b8d16a6918030d09fc2

The big RosBE 1.5 compatibility patch. You will need RosBE 1.5 from this point!
- Set the minimum GCC version to 4.4.0 and minimum Binutils version to 20091016.
- Remove the -fno-unit-at-a-time hacks.
- Remove dgorbachev's temporary hacks for user-mode C++ applications.
- Merge ntoskrnl's "precomp.h" and "ntoskrnl.h" again, the PCH issues have been fixed.
- Use our "ofmt_stub.a" to be compatible with newer MinGW Runtime versions.
- Use LD's new -exclude-all-symbols option to not auto-export all symbols in case no DEF file or __declspec(dllexport) was specified.
  We used to patch our LD version to work around this problem.
- Use LD's --start-group and --end-group parameters to allow a more flexible linking order.
- Use GCC's -fno-set-stack-executable for amd64 and i386 targets to disable adding the __enable_execute_stack code.
- Change the makefile's name to "makefile-$(ARCH).auto" for all architectures.
- Remove some -Wno-error flags.

See issue #4810 for more details.
