Glibc does not build: asm/page.h not found As of linux-2.6.25, asm/page.h is no longer exported. This means the glibc up to and including 2.6.1 will not build against headers exported from linux-2.6.25 and up. Status of glibc-2.7 and above is unknown. ---- dmalloc does not build This broken build has been observed for big endian ARm with glibc and NPTL, and with i686 with glibc and NPTL. This has not been fully investigated yet. There is a name clash with strdup, where it is a macro somewhere, and dmalloc tries to re-declare a strdup function in dmalloc.h, but the declaration is overwritten with the macro expansion, and thus the build is broken. The common denominator seems to be NPTL.
