When using cygwin/MinGW I get the following :- /cygdrive/e/mozilla/source/mozilla/build/cygwin-wrapper g++ -mno-cygwin -o gfxAl phaRecovery.o -c -DIMPL_THEBES -DMOZILLA_INTERNAL_API -DOSTYPE=\"WINNT5.1\" -DO SARCH=WINNT -I../../../dist/include/cairo -I../../../dist/include/libpixman -I. ./../../dist/include/string -I../../../dist/include/pref -I../../../dist/include /xpcom -I../../../dist/include/unicharutil -I../../../dist/include/lcms -I../../ ../dist/include -I../../../dist/include/thebes -I../../../dist/include/nspr -I../../../dist/sdk/include -fno-rtti -fno-exceptions -Wall -Wconversion -Wpointer-arith -Wcast-align -Woverloaded-virtual -Wsynth -Wno-ctor-dtor-privac y -Wno-non-virtual-dtor -Wno-long-long -pedantic -mms-bitfields -pipe -DNDEBUG -DTRIMMED -O -I../../../dist/include/cairo -DWINVER=0x501 -D_WIN32_WINNT=0x50 1 -D_WIN32_IE=0x0500 -DX_DISPLAY_MISSING=1 -DMOZILLA_VERSION=\"1.9b3pre\" -DMOZI LLA_VERSION_U=1.9b3pre -DHAVE_SNPRINTF=1 -D_WINDOWS=1 -D_WIN32=1 -DWIN32=1 -DXP_ WIN=1 -DXP_WIN32=1 -DHW_THREADS=1 -DSTDC_HEADERS=1 -DWIN32_LEAN_AND_MEAN=1 -DNO_ X11=1 -D_X86_=1 -DD_INO=d_ino -DSTDC_HEADERS=1 -DHAVE_DIRENT_H=1 -DHAVE_GETOPT_H =1 -DHAVE_MEMORY_H=1 -DHAVE_UNISTD_H=1 -DHAVE_MALLOC_H=1 -DHAVE_LIBM=1 -DNO_X11= 1 -DMMAP_MISSES_WRITES=1 -DHAVE_STRERROR=1 -DHAVE_SNPRINTF=1 -DHAVE_MEMMOVE=1 -D HAVE_RINT=1 -DVA_COPY=va_copy -DHAVE_VA_COPY=1 -DMOZ_EMBEDDING_LEVEL_DEFAULT=1 - DMOZ_EMBEDDING_LEVEL_BASIC=1 -DMOZ_EMBEDDING_LEVEL_MINIMAL=1 -DMOZ_SUITE=1 -DMOZ _BUILD_APP=suite -DMOZ_XUL_APP=1 -DMOZ_DEFAULT_TOOLKIT=\"cairo-windows\" -DMOZ_T HEBES=1 -DMOZ_CAIRO_GFX=1 -DMOZ_STATIC_MAIL_BUILD=1 -DMOZ_DISTRIBUTION_ID=\"org. mozilla\" -DOJI=1 -DIBMBIDI=1 -DMOZ_VIEW_SOURCE=1 -DMOZ_XPINSTALL=1 -DMOZ_JSLOAD ER=1 -DNS_PRINTING=1 -DNS_PRINT_PREVIEW=1 -DMOZ_NO_XPCOM_OBSOLETE=1 -DMOZ_XTF=1 -DMOZ_MATHML=1 -DMOZ_ENABLE_CANVAS=1 -DMOZ_SVG=1 -DMOZ_SVG_FOREIGNOBJECT=1 -DMOZ _UPDATE_CHANNEL=default -DMOZ_FEEDS=1 -DMOZ_STORAGE=1 -DMOZ_LOGGING=1 -DHAVE___C XA_DEMANGLE=1 -DHAVE__UNWIND_BACKTRACE=1 -DMOZ_USER_DIR=\"Mozilla\" -DHAVE_STDIN T_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_UINT64_T=1 -DMOZ_PROFILELOCKING=1 -DMOZ_RDF=1 - DMOZ_MORK=1 -DMOZ_DLL_SUFFIX=\".dll\" -DJS_THREADSAFE=1 -DMOZILLA_LOCALE_VERSION =\"1.9a1\" -DMOZILLA_REGION_VERSION=\"1.9a1\" -DMOZILLA_SKIN_VERSION=\"1.8\" -U WIN32_LEAN_AND_MEAN -D_MOZILLA_CONFIG_H_ -DMOZILLA_CLIENT /cygdrive/e/mozilla/so urce/mozilla/gfx/thebes/src/gfxAlphaRecovery.cpp In file included from ../../../dist/include/thebes/gfxContext.h:45, from ../../../dist/include/thebes/gfxAlphaRecovery.h:41, from e:/mozilla/source/mozilla/gfx/thebes/src/gfxAlphaRecovery. cpp:39: ../../../dist/include/thebes/gfxColor.h:64:24: byteswap.h: No such file or direc tory make[6]: *** [gfxAlphaRecovery.o] Error 1 This problem is associated with a patch for Bug #406580

Jag's patch in bug 406580 fixes this build issue, but after that I get another build error, I filed bug 411055 for that.

Now that bug 413143 has landed, can you verify that this problem has gone away?

Yeah, sorry for not testing this yet. I usually don't update my mingw build a lot. I'll try to do that in the next couple of days and will resolve this bug accordingly (if it's indeed fixed).

Nothing to be sorry for, I only just checked it in ;-)

Not sure if this is fixed, after updating my build and rebuildig, I got the build error in bug 414971.

I assume this was addressed, there's been no activity since jan/08.
