While it was bootstrapping fine on 2006-10-21, mainline now fails to build on my mingw setup because libgomp wants to run makeinfo, which I don't have. It says make can be buggy, but it's not (it's GNU make 3.79.1).
if /home/coudert/trunk/missing makeinfo --split-size=5000000 -I ../../../trunk/libgomp/../gcc/doc/include -I ../../../trunk/libgomp \ -o libgomp.info `test -f 'libgomp.texi' || echo '../../../trunk/libgomp/'`libgomp.texi; \ then \ rc=0; \ else \ rc=$?; \ $restore $backupdir/* `echo "./libgomp.info" | sed 's|[^/]*$||'`; \ fi; \ rm -rf $backupdir; exit $rc WARNING: `makeinfo' is missing on your system. You should only need it if you modified a `.texi' or `.texinfo' file, or any other file indirectly affecting the aspect of the manual. The spurious call might also be the consequence of using a buggy `make' (AIX, DU, IRIX). You might want to install the `Texinfo' package or the `GNU make' package. Grab either from any GNU archive site. make[2]: *** [libgomp.info] Error 1 make[2]: Leaving directory `/home/coudert/ibin/i386-pc-mingw32/libgomp' -- Summary: [4.3 regression] build fail in libgomp because makeinfo is missing Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgomp AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: fxcoudert at gcc dot gnu dot org GCC build triplet: i386-pc-mingw32 GCC host triplet: i386-pc-mingw32 GCC target triplet: i386-pc-mingw32 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30546
