Source Hack to complie on modern compiler

Some modern compiler does not accept plain2's source. And compiled program may cause running error if you can compilt that. I met such problem with gcc 4.4.6 on CentOS 6.2 .

plain2 modifies data area. Modern compilers dislike it. These programs expect that data area is constant. Then, the duplication those on heap area from data area avoids this problem.

Here, a sample of source hack. Own your risk.

1. edit macro.c; add the loop of duplication. You can see that marked with #if 1 and #endif in following source fragment.

   initMacroDefs(mcp) struct macDefs *mcp; { #if 1 char * Xstrdup(char *src); char *work; struct macDefs *firstmcp; firstmcp = mcp; /* save */ while(mcp->mdef_number >= 0) { if (outMacro[mcp->mdef_number] == NULL) work = Xstrdup(mcp->mdef_def); mcp->mdef_def = work; mcp++; } mcp = firstmcp; /* restore */ #endif while(mcp->mdef_number >= 0) { if (outMacro[mcp->mdef_number] == NULL) outMacro[mcp->mdef_number] = macroParse(mcp->mdef_def, mcp->mdef_number, mcp->mdef_def); mcp++; } }

2. add Xstrdup()

   char * Xstrdup(char *src) { char *dst; dst = (char*)malloc(strlen(src)*2+1); strcpy(dst, src); return dst; }

   no garanty of the length (currently double size.) I can only say "It is work in my situation." You may enlarge that.
