The compiller requires write access to library files for compilation (?)

[t-w]

I have built the compiler (1.6.6) on Linux (using FreePascal) and manually installed it system-wide (somewhere in /opt/...). Initially it was working - but then I changed file permissions so that a regular user cannot access the compiler/library files for writing (precisely - I changed the file ownership from a regular user to root/admin - as it should be on a regular multiuser system) - and the compilations started failing, with rather strange errors, from:

/opt/retro/madpascal/lib/crt.pas (1,10) Error: Syntax error, '.' expected but 'unknown token' found

or

/opt/retro/madpascal/lib/types.pas (446,5) Error: Syntax error, '.' expected but 'END' found

to errors with "Access violation" (like the one in #112).

Using strace revealed (it doesn't matter if it is for C64 or Atari):

$ strace -o /tmp/output2 mp -t c64 a_test0.pas -ipath:/opt/retro/madpascal/lib

[...]

$ less /tmp/output2
[...]
access("/opt/retro/madpascal/lib/crt.pas", F_OK) = 0
stat("/opt/retro/madpascal/lib/crt.pas", {st_mode=S_IFREG|0644, st_size=3929, ...}) = 0
access("/opt/retro/madpascal/lib/crt.pas", F_OK) = 0
stat("/opt/retro/madpascal/lib/crt.pas", {st_mode=S_IFREG|0644, st_size=3929, ...}) = 0
access("/opt/retro/madpascal/lib/crt.pas", F_OK) = 0
stat("/opt/retro/madpascal/lib/crt.pas", {st_mode=S_IFREG|0644, st_size=3929, ...}) = 0
open("/opt/retro/madpascal/lib/crt.pas", O_RDWR|O_LARGEFILE) = -1 EACCES (Permission denied)

so the compiler indeed tries to open a library source (unit) for writing during compilation, and the compilation fails if it cannot...

A rather strange, not very safe behaviour, it would be good if it was corrected.

Compiler does not require write access to library files to compile

try 1.6.8

Yes, it still does. Fix above.
