Bug ID: 100014
Summary: MSDOS DJGPP host endian unknown
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: unlvsur at live dot com
Target Milestone: ---
Configuring in ./gcc
configure: loading cache ./config.cache
checking build system type... x86_64-pc-linux-gnu
checking host system type... i586-pc-msdosdjgpp
checking target system type... i586-pc-msdosdjgpp
....
...
checking whether byte ordering is bigendian... unknown
configure: error: unknown endianness
presetting ac_cv_c_bigendian=no (or yes) will help

Looks like AC_C_BIGENDIAN tests various macros and falls back to runtime checks
which don't work when cross-compiling.

--- Comment #2 from Andreas Schwab <schwab@linux-m68k.org> ---
According to the autoconf docs, it should work also when cross-compiling:
This macro runs a test-case if endianness cannot be determined
from the system header files. When cross-compiling, the test-case
is not run but grep'ed for some magic values. ACTION-IF-UNKNOWN
