| |
From: Tom Enderes <enderes@gmail.com>
The kernel build failed on cygwin hosts, because cygwin has slightly different typedefs compared to linux: scripts/mod/file2alias.c:518: error: dereferencing pointer to incomplete type Two files, scripts/mod/file2alias.c and scripts/mod/modpost.h, were modified as follows: Whever __CYGWIN__ is defined, __uint32 is defined as __uint32_t (instead of uint_32_t) and the missing ElfxxSection definitions are added. These changes have been tested both on cygwin 1.5.24, hostcc=gcc 3.4.4 and on FC5, hostcc=gcc 4.1.1-1. Any tests on cygwin, with and without this change, were executed with the following set for make: HOST_LOADLIBES="-lcurses -lintl".
