Building egcs-1.1.2 for DJGPP requires LFN support. Removing this limitation
may require large amount of work. Even without that we'll have enough 
problems with upcoming version.

Please note that then we'll get /dev/env also in dependencies generated
by "gcc -M". As result also make and maybe something else must understand
/dev/env/...

There are some things that could be done with egcs-1.1.2 distribution for DJGPP:
	- adding -imacros=... to specs
	- moving  lang/cxx/headers.gcc from gppe112b.zip to gcce112b.zip and
          modifying specs to use it as told in readme.djgpp
       - cross-compiling stuff in egcs112s.zip. Currently modified collect2.c does not
          compile under Linux when building cross-compiler. Also perhaps some
          scripts for building cross-compiler would be nice
       -  cleaning source archives from names invalid without LFN support (I did it 
          partially with libraries, but not gcc. Currently I haven't touched that for
          about a month). Support of building without LFN support is next and more
           difficult step. 

There is no problems with first 2 things.
