A patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:
Here is another patch to hopefully enhance rtems' configuration.
Motivation: Try to support other c-compilers besides gcc (I tried to
build rtems under Solaris using sun's WSPro c-compiler).
Here is a couple of small patches concerning the host compiler
configuration, which fix/work-around the worst problems when using sun's
WSPro c-compiler.
Changes:
* Replaced make/compilers/gcc.cfg with make/compilers/gcc.cfg.in, ie.
gcc.cfg is generated by configure now.
* Removed a line containing a hard-coded "gcc" from gcc.cfg (BUG-fix).
* Add -g to host compiler flags only if configure reported -g to work
* Add -Wall to host compiler flags only if configure reported that the
host compiler is gcc (WSPro's cc chokes on -Wall).
* Some modifications to make/Makefile.in
* Adapted make/custom/default.cfg to the new location of gcc.cfg
BTW, gcc.cfg/gcc.cfg.in seems to be full of unused code (DEBUG-VARIANTS
etc.) which deserves to be cleaned up, IMO.
IMO, a similar patch should be applied to gcc-target-default.cfg
