In GUB? In a special config file in the LILYPOND source tree? I do not see much trouble, if support for processors before pentuim4 on Windows is dropped. I would have no problem. When working on the command line options for 32 bit Windows compilation, you may consider the LARGEADDRESSAWARE problem, too: Unitl now the memory usage of lilypond.exe is limited to 2 GB. I mutally modified this flag in the EXE file and became able to compile my most huge scores (more than 200 pages) - thus lilypond.exe is LARGEADDRESSAWARE today, but it is not declared to be so. MINGW only offers a linker option to set this flag, but no tool to modify it after linking. Command line option for SSE2 usage, as far as I configured it out: -march=pentium4 -mfpmath=sse -msse2 Command line option for gcc to set LARGEADDRESSAWARE during linking: -Wl,--large-address-aware ArnoldTheresius -- Sent from: http://lilypond.1069038.n5.nabble.com/Dev-f88644.html
